Press X To Jason

A reference to Heavy Rain. At the intro, pressing X will cause the main character to shout for his son, Jason.

Guy 1: Hey, I'm playing Heavy Rain.
Guy 2: Isn't that the Press X To Jason game?
Guy 1: Yes
Both at the same time: JAAAAAAAASON!

Xtoner 

Said of a guy/chick that used to smoke a lot of dope but don't do it anymore (or have dramatically reduced their smoking).

-Mate, that bird is reeeally cool. The thing is, she forgets stuff, she is a xtoner.
-Me, myself and I are xtoners too!
-Respect.

xton 

A button on the graphing calculator. The 'o' isn't actually an o, it's some kind of greek letter that looks like an o with a line through it. People say it's used for entering variables, but it really sends a signal to the alien Xton who will come and dominate our civilization in the year 3496

I just pressed the xton button. Your descendents will all be slaves
