To pound a vagina with furvor. Usually stated by a male who is sex starved, and eager to pound a hole. Can be also be used as a reference to a desire for hatefuck.
Q: Hey, are you going out on a first date with that girl tonight?
A: Yeah, I hope she's ready, because i'm going to get her drunk and PTH - Punish that/the hole
A statement to be said in a group setting whenever one pleases. Getting the attention of the group is crucial, and so is looking up in a disgusted way. An actual hole in the ceiling is recommended, but not necessary.
(Looking up curiously) Wait so........is that a rathole??
