I am 12 and what is this? 

A phrase used to indicate that the user finds someone else's comment, picture or video to be inappropriate or otherwise NSFW.

Rarely used to indicate any actual offense; rather, it's almost always presented as humor or sarcasm, or by trolls trying to stir the pot. Most people tend to report any actual terms of service violations, rather than simply commenting.

Almost never used by actual 12-year-olds, who are technically too young to be on most social media sites anyway.

Person A: *posts a meme featuring daVinci's Venus de Milo*

Person B: I am 12 and what is this?
