The Wrecking Ball–someone who lunges in so hard they clank their teeth against the other person’s, breaking more than the moment and possibly leaving their partner with the smile of a hockey player.
The Meat Grinder–someone who forgets (or doesn’t care) that they have braces and like a Saw film proceeds to attack their partner’s tongue and lips with their cheese grater grill.
Vlad the Impaler–someone who repeatedly shoves their Gene Simmons-sized tongue down their partner’s throat, testing their gag reflex.
