Bucking-Kinda the same as curving someone, making someone else feel scared, or not wanting to do something G, or cool. Used in the south, watch out a lot of friends will say your bucking just because you don't want to do something they want!!!
boy 1: I don't want to fight you
boy 2: oh so you bucking
You would probably get respect if you didn't buck from every call out.
Whats sup, Im not bucking
