When playing a game of Halo or Halo 2, you biff (smack them) in the back with the flag, killing them on contact.
You assassinated New001.
"OOOH you see that sucka?? That was a flag biff you freaking noob"

What you say when someone is being a genuine freak
Ye fresh biff
noun- is when you sleep with a blonde, brunette, and a redhead in the same night.
"Maddie, Suzan, and Heather are all here tonight, I could totally achieve a victory biff and fulfill the prophecy."
A dirty, crusty old rag that you ejaculate into.
I gotta get down to Walmart to purchase some picture frames. For what you ask? To frame my biff rag of course.
