Annual do not do what Jem says day. 

A day, so holy and strictly followed, where all who know what is good for them, hate Jem. Jem and his imbecilic suggestions are not to be endorsed, but rather abrogated at any cost. Jem on this day, knows nothing.

Jem: 'You should watch it.'
You: 'Never.'
This, is Annual do not do what Jem says day.

That's what she said 

A followup phrase that can possibly make just about anything someone just said funny or horribly unfunny.

Despite what anyone says, this shit is still funny.

Are you through yet? I am getting tired of holding this.

Yeah, that's what she said.

Wayne's World 1991. Possibly the first time this was uttered on the silver screen, or at all for that matter.

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?
