nuck is kinda what a horse does when it's mad. so when a human
nucks, then they kinda of do a crazy body movement such as kicking, jumping, jabbing, nodding the head vigorously, etc....
buck is kind of a short way of saying
buck wild or getting crunk.
so basically, it means to get crunk and go crazy if you're a wild type of person. This is mostly done when listening to rap music, dancing in the club, or getting into a fight.
-Nuck if you
buck boy.
-If he get up in my face, I'm gone start
nucking on him.
-she acting like she buck, but if she say something else to me, then I'm gone
nuck her a**!
