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
