I'm 12 years old and what is this? 

Internet meme that came about after some kid said it on a comment when Youtube.com was raided with porn. Usually said after something that adults talk about/kids wouldn't get. Not to be said in real life, like most other memes.

Anon A: I was wondering, do you guys prefer anal sex or vaginal sex?

Anon B: I'm 12 years old and what is this?
