slapper

One who, or that which, slaps.

A prostitute.

A fella looking dapper / And he's sittin' with a slapper / Then I see it's a pimp / And his crack whore

You've got a photo of the dead grandad, no pic of the blonde slapper?

A woman of loose morals.

A type of detonator which uses a powerful surge of electricity to vaporize a thin metal foil, propelling a larger piece of plastic film at a speed high enough to detonate an explosive upon impact.

Anything monstrous; a whopper.
