A "couple" who can been seen making out at parties together, hanging out at school/each other houses, going to the movies, etc. BUT they insist they aren't dating, mostly because they want to bang other people. Hence why they're officially unofficial.
Dude 1: Whoa, check it out. Matt and Allie are making out again!
Dude 2: Yeah man, they've been officially unofficial for, like, 3 years.
Inspired by the inexplicable Soulja Boy hit, Crank Dat. Occurs after a burn, often yelled out by a third party. Directed at the person who dissed as props for a sweet burn. May be exaggerated or diminished depending on how insulted the person is.
Alex: Hey man...why are you wearing a red hat?
Mark: I dunno, it's cool?
(Brian enters room)

Alex: aw YOOOOUUUU!!!
Mark: ...fuck you guys *takes off red hat*
