Any fist pound between bro's that is used to indicate mutual agreement of opinion, in lieu of "Amen," "Word," or similar exclamations. Can be abbreviated as "TFP."

Bro 1: "Dude, you haven't found a job yet either?"
Bro 2: "Naw, man, I just sit around and play video games all day."
Bro 1: "Haha, me too, bro! Terrorist fist pound!!"
(They pound their fists together.)
