An acronym for 'For da boizzzzzz'. A very important principle which dictates that everything you do, you do it to make your boys, or some might say, your wolf pack, proud.
Females come second when 4DB comes into play.
1. "Dude, did you just do a 65 second kegstand?"
"I did it 4DB (mumbles while puking and passing out)"
2. "Frankie, your a class act... You grinded with, and even make out closed that 300 pound whale, just to wingman, so Tommy didn't get cockblocked, and he could wheel that cutie."
"I did it 4DB bro."
