Twelvie

Twelvies are (usually) 11-13 year old kids who, essentially, think they're more important/grown up than they really are, when actually these attempts at being more 'cool' and 'mature' just make them look less mature to those who actually are. They're quite naive and act like they know everything, when in fact, they don't. They often overuse stupid words such as 'swag'.

Twelvie: Look at me, I've got a boyfriend, I'm practically an adult now. Swag.

Twelvies 

A twelvie is a person that is between 12-14 who thinks they are cool and they fucking know everything, especially the girls who think they are hot shit and wear crop tops to the dairy. Twelvies usually think they are cool hooking up with people or going to parties. Twelvies are fucking annoying and they think they are better than everyone else. Twelvies are also known as teenie boppers. Fucking teenie boppers.

tweeving 

Pronunciation:\ˈtwēvŋ\

Function: verb

The act of updating your twitter status while driving down the road and inadvertently swerving and weaving, in and out of your lane, as though you were intoxicated without a care in the world.

Bobby Joe, tired and bewildered after a long day at his job, realized another clever observation on his gridlocked commute home.

Grabbing his iPhone, Bobby Joe began a historic tweeving run, nearly running 3 vehicles and a motorcycle off the highway as he tweeted, "I'm tired, bewildered and commuting in the WORST traffic! No way I get home and see Dancing with the Stars in time. Time to get Tivo."

Twelving

The act of taking a #1 out of where you normally take a #2. It's a nice way of saying you have liquid diarrhea.

I ate some undercooked chicken yesterday and have been on the toilet twelving all day.

Twelvie bitch 

A twelvie bitch is an eleven year old girl who is pretending to be a twelvie, when she isn't even on that level yet, unlike the people the grade above her. She will have Instagram which she will update regularly with selfies of her and her BFFL. She has one or two baes and will beg her parents to drop her at the mall, only to take lots of selfies with her baes and tag them in the photo. Expect, even in the middle of winter, to have slutty lace tops and miniskirts, and don't forget the make-up! She will often comment on her friends profiles with a '😍 so pretty bae'. Comes in the form of Ashleys, Georgias, Lanas and Halles.

Stupid twelvie bitch

Twelvie Baggage 

When a celebrities fan base is comprised of so many young girls that it is off putting.

I would be a fan of One Direction, but they have too much twelvie baggage.
