(music) A bass guitar technique of hitting a string hard with the side of the thumb knuckle, producing a loud but brief snapping sound. Slapping is usually combined with popping, the act of pulling a string outward with the finger tip and letting it snap back. Invented by Larry Graham (Sly and the Family Stone, Graham Central Station).

Slap & pop bass sounds are very characteristic of disco and funk music, though around 1990 it got very popular again when bands like Red Hot Chilli Peppers, Primus, Infectious Grooves, and Faith No More hit the hard rock radio stations and Mtv.
Jazz players on upright bass (aka double bass) have a technique called "slapping", but it's a completely different technique that involves literally slapping the strings.

Said when someone does something stupid or wrong, sometimes accompanied by slapping on the top of hands. Can be negated by saying "no slaps" before someone else says it.
Bob-"Man, this is a good pizza cake..I mean piece of cake"
Jim-"Slaps! ahahaha"
Bob-"..."
Alternate example:
Bob-"Man, this is a good pizza cake..I mean piece of cake, no slaps."

A small water park in Lisle, Illinois.. The first year it opened was great because all the guy lifeguards were banging the girl lifeguards at will.
I worked at SLAP and banged some bitches that worked there. We also drank a lot and smoked a lot of weed, quite frankly, everyone had a blast.

A way of keeping your seat safe when you get up without anyone taking it. Sort of like fives, but for as long as you want. When you get up yell out slaps and slap your seat,
Slaps!
