That is SO going on Facebook! 

The 21st century equivalent of calling something a "Kodak moment." It's not only good enough to photograph, but you are compelled upload it to your wall on Facebook for all to see.

"Look! That poodle is doing the Macarena!"

"That is SO going on Facebook!" (pointing smartphone and clicking away)

That is so second millennium 

Conveniently making use of the fact that a milennium has recently passed to exaggerate how out-of-date something is.

Cole: I just went to the mall and bought Clerks II DVD today. You wanna come over and watch it?

Derek: You actually BUY your movies? That is so second millennium!

That is so embarrassing 

When someone had tried their best to embarrass you but then forget you have not been born with a silver spoon up your arse.

OMG, that is so embarrassing, I would never go out with him, I wouldn’t know where to put my face.
