Ag
Alternate spelling of the word Agg. A word that kids from the OC use because they are too Ag to say "cool". The word Ag can be used to replaces pretty much any slang, for example: cool, awesome, badass, sweet, and even some negative words like shit, fuck, or damn it.
"We're getting pizza? Oh, Ag! I love pizza! Pizza is so Ag!"
or on the negative side, "Ag me, the pizza place is closed." and "The pizza place is closed all next week? Oh Ag."
