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.

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.

Twelvesome 

1. When twelve people somehow manage to have sex together.
2. THE BEST GROUP OF FRIENDS. EVER.

Mandy and Lisa were sitting home alone when 10 boys showed up at their door. Each was shirtless and the girls smiled as they walked straight upstairs to their bedroom. On the way up they began stripping and tossing their clothes down. As the girls entered their room, the boys were sitting there waiting for them. The girls began kissing each one as they stripped each one individually. After the boys were all naked they decided to take turns eating the girls out. By the time they all had a turn, Mandy had already orgasmed twice, and Lisa four times. Now Mandy laid down and took one dick in each hand, giving two boys handjobs. She then allowed one guy to penetrate her vaginally, another anally. Another boy was having mammary sex with her, as two others each sucked on one of her tits while simultaneously jerking off. Then Lisa sat on her face, and Mandy began to eat her out. Lisa then took two cocks in each hand and gave two boys handjobs, while she gave the last one a blowjob. The first two boys getting handjobs came on Mandy's face, the one having mammary sex came on her chest, the two sucking her breasts came on her stomach, and Lisa came on her face. The other two boys having handjobs came on Lisa's face, as the one getting a blowjob came in her mouth. Mandy rubbed the cum off her stomach, chest, and face and ate it. She orgasmed in pleasure as the two penetrating her came at the same time. It was the best twelvesome ever.

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
Look at all the twelvie bitches

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.

Twelvie

A person that is of the age 12. They think they're top sh*t. They think they own the place. They think they can win fights. They think they can do whatever they want. They act like there 16.

Wow that kid is such a twelvie.
