Tweenty 

Someone who is somewhere in their late teens through early twenties, when they know everything and are absurdly idealistic.

I can't wait until he is no longer a tweenty and not such a d-bag.

thick and pasty twenty-wiper

When you take a massive dump that makes you wipe your ass so many times you end up using half a roll of toilet paper

Friend: Damn! You were in the john forever.

Me: Dude, it turned into be a thick and pasty twenty-wiper.

Twenty Stick-Boobs 

Another way of writing the year "2013".
The "3" looks a bit like a pair of boobs as viewed from the top.

Works best when written, vs. when spoken.

07-21-13 {or "21 Jul 2013", or even "Jul. 21, Twenty Stick-Boobs" if you prefer}. Just making my daily check-in from Federal Way WA. USA...

Twenty9United 

A legend in the FT community. Always there for people when they need him the most. He’s probably the biggest Kai Havertz in the world and he’s the Leverkusen admin’s best friend.

Twenty9United is the goat.

Twenty9United by a pseudonym was here before June 23, 2020

twentytard 

Any guy over the age of nineteen that is NOT really mentally retarded and STILL lives with mommy and daddy, has no job, no car, finds a girlfriend online then has to depend on his parents to pick that girl up AND pay for everything.

As the girl watched the clock pass another hour beyond the promised time, she got a text from her twentytard boyfriend stating his mommy was still sleeping and the date wasn't happening.
