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?

I'm only 12 and I'm listening to this song

A comment often left on older youtube music videos. A way for kids to congratulate themselves for listening to a song that is usually older than they are. They believe that this fact makes them better than everyone else, and smarter than anyone who listens to today's pop music.

Kid: OMG I'm only 12 and I'm listening to this song. I was born in the wrong generation!!!
