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**!

Get the knuck if you buck mug.
When a girl sucks a guys penis until he "bucks" (comes). Then the girl gags from it and accidently bites down on the penis. The guy then shoves cake in her face to try and get her off. Usually occurs during Spicy Cakes and Sour Cakes.
