10 millennial habits that Gen Z is already mocking

Cultural trends age faster than people, and today, Gen Z is holding up a mirror to the millennial habits that suddenly feel stuck in the past.

Generations always clash over culture and fashion trends as time passes. Millennials once rolled their eyes at baby boomers, and now the tables have completely turned. Younger folks born after 1996 are loudly pointing out the outdated quirks of people in their thirties. This generational shift creates a hilarious cultural gap visible across every social media platform.

It feels like just yesterday that side parts and skinny jeans ruled supreme. Now, a fresh crop of teenagers and young adults dictates the rules of cool on the internet. They spot older habits from a mile away and playfully roast them without mercy. Keep reading to see exactly which trends have officially lost their cool factor.

Using the Laughing Crying Emoji

Younger internet users consider the classic tears of joy face a massive digital red flag. If you send this yellow face to a teenager, they will immediately know your exact age. They prefer the skull face to indicate they are dying of laughter.

According to CNN, Gen Z users find the laughing crying emoji completely outdated. They view it as a relic of a bygone era of early smartphone messaging. Switching to the skull icon might save you from a few jokes in the group chat.

Rocking Skinny Jeans Every Day

Tight denim pants held a tight grip on millennial wardrobes for over a decade. A report by Sourcing Journal showed that 73 percent of Gen Z teens prefer baggy or wide-leg jeans over skinny fits. This younger group prioritizes comfort and movement over looking painted into their clothes.

Baggy cargo pants and relaxed mom jeans dominate the fashion scene right now. Millennials refuse to let go of their fitted clothes because they grew up thinking loose clothes looked sloppy. You can spot the generational divide just by looking at the leg widths in any crowded room.

Parting Hair on the Side

The deep side part was a staple for anyone who grew up during the early days of social media. Younger crowds have declared that the middle part is the only acceptable way to style your hair today. Changing your hair completely alters your facial symmetry, and younger people swear by the center split.

Many thirty-somethings feel incredibly naked with a middle part because it exposes their face differently. They cling to the dramatic side swoop that defined their high school years. Despite the teasing, some older folks stubbornly refuse to update their daily morning grooming routines.

Overusing the Word Adulting

Complaining about paying bills and buying groceries used to be a quirky personality trait. A 2025 YPulse study revealed that Gen Z respondents find the concept of adulting incredibly cringeworthy. They simply view doing chores and paying taxes as regular life rather than a special achievement.

Older people often congratulate themselves for completing basic survival tasks with this specific verb. The youth see this as a refusal to grow up and accept standard responsibilities. Simply doing your laundry does not earn you a trophy in the eyes of younger generations.

Obsessing Over Harry Potter Houses

Basing your entire personality on a fictional wizard school feels very dated to the modern youth. The New York Times reports that millennials love Harry Potter a lot, and Gen Zers hardly do. The newer crowd simply moved on to different fictional universes and fresher pop culture references.

Declaring yourself a Hufflepuff on a dating app profile is now seen as a major social mistake. People under twenty-five prefer astrological signs or personality tests to explain their quirks. If you still wear a scarf in your house colors, you might be showing your age.

Performing the Millennial Pause

There is a tiny hesitation at the beginning of video recordings that older creators always do. They wait a split second to make sure the camera is actually rolling before speaking. Younger creators start talking the exact millisecond they hit the record button to keep pace fast.

Some Gen Zers may think millennials take themselves too seriously on social media formats. That tiny breath of dead air gives away a creator’s birth year instantly. Skipping that awkward silence makes videos feel much more authentic and energetic.

Taking Selfies From High Angles

Holding the camera way above your head used to be the ultimate trick for a flattering photo. People did this to make their eyes look bigger and hide any hint of a double chin. Today’s youth prefer capturing themselves straight on or even from slightly below the chin.

The high-angle shot screams of insecurity to a generation that values raw authenticity online. They deliberately post blurry or chaotic photos to reject the polished aesthetics of the past. Dropping your phone down to eye level instantly updates your digital persona.

Using Slang Words Like Doggo

Baby talk for animals was incredibly popular on internet forums about ten years ago. If you say look at that cute doggo, a teenager will probably ask why you are talking like a toddler. They prefer using normal words for pets rather than speaking in a forced internet dialect.

The whole aesthetic of cute internet animal speak has lost its charm entirely. Younger pet owners just call their animals by regular names without the extra baby vowels. Typing out long paragraphs of baby talk will instantly get you mocked in the comments section.

Posting Perfectly Curated Avocado Toast

Snapping a highly edited picture of brunch used to be the peak of weekend internet activity. Gen Z often prefers unfiltered, authentic photo dumps over perfectly curated pictures. They want to see the mess of real life instead of a staged dining table.

Taking ten minutes to get the lighting right on a piece of bread seems ridiculous now. People just want to eat their food while it is still warm and enjoyable. Throwing a random blurry picture of a half-eaten sandwich online is much more socially acceptable.

Complaining About Mondays Online

Posting a meme about needing coffee to survive the start of the week is a tired trope. Younger workers find this constant complaining about the corporate grind to be highly unoriginal. They handle their workplace frustrations through sarcastic humor instead of sharing generic cartoon images.

The whole coffee addict persona feels like a substitute for having an actual personality. Teenagers and young adults prefer to joke about existential dread rather than simple fatigue. Finding a new way to express your tiredness might save you from a few eye rolls.
