When someone is being a total douche bag, the correct response would be:
"Fuck off, man."
But since that's gotten pretty old, a new alternative has arisen:
Blow Dogs For Quarters or BDFQ

It is a way to entirely humiliate and demoralize said douche bag.
"Hey man, guess who got laid last night? NOT YOU!"

"BDFQ."
