When you are in a public toilet and you must squat over it and shit as the seat is mank, the Pottykiss is when you accidentally squat too low and make contact with the grimy seat
I was just in the skanky bathroom when, what do you know, I Pottykissed that manky ass seat
When you bang a man's head off the urnal
Jimmy- "Dave's going to use the bathroom" larry- "BRB gonna go beat his ass" jimmy- "what r ya gonna do?" Larry- "Give him a PottyKiss"
