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"
or
"Buck Buck
homie"
or
"Buck Buck (alone)"
or
"Buck Buck nigga.. why you
duckin me?"
