When one plays music with a lot of bass and slang, roles down the windows, and turns the speakers on blast so all the BITCHES can hear.

an equivalent of dope, awesome, delicious. Usually used for food, a dish can be "slappin" like it's so good that if someone disputes its awesome godliness they are in for a slappin. Can also be used in the form of a verb to describe something's slappy awesomeness.

Yo you should head down to Dave's food truck, the pulled pork is slappin I love eating at that Hawaiian terryaki place, everything on the menu slaps
