A game in which two individuals each take a shot of vodka but DO NOT SWALLOW. They alternate slapping each other in the face until one person, the loser, either spits out the vodka or swallows it.
John and Adam were playing vodka slap. John missed on the first swing and really just sort of punched Adam. But that made John laugh and he spit out his vodka, thereby losing vodka slap.
