a dance style named after famous Jamaican dancer Bruck Up, a choreograper who appeared in videos with artists like Wyclef, Busta Rhymes, and Patra. His style is very hard to emulate, he rocked the dance halls in the 90's, people coming from miles away to see him dance, and to battle his style.
Used to describe women walking in a strangekind of waddle. Often a fat or dumpy legged woman who simple cannot walk with her legs closer than 2 foot apart.
Buck up means to basically grin and bear it, kinda like sayin "get over it" only more nicely. It's especially used in the south and often in small towns.
Mark was complainin about the rain ruinin the huntin trip and his dad said "it'll be ok, just buck up"
