The sweetest game ever created. Talked about by Bill Cosby in his stand up comedy. It is when you get a group of guys to crouch down and hold on to a fence or poll and see how many guys you can get to jump on them before it collapses. When aproaching the mound of people you need to yell out "BUCK BUCK number(whatever number you are)."
"BUCK BUCK NUMBER 2!"

Man that was an insane game of Buck Buck, my knee got all busted up.

It is a greeting for hello; what's up; what's going on; or as a calling for other people familiar with the term. It originated on Cleveland's (Ohio) eastside. Originally, this was an inside joke. A couple of friends were drinking and one person went to say " what's up", but started to slur his words and buck buck, came out instead. We started to use the words to make fun of the guy, but eventually, it became a standard in our vocabulary.
"Buck Buck Nigga what's good"

"Buck Buck homie"

or

"Buck Buck (alone)"

or

"Buck Buck nigga.. why you duckin me?"
