rule 404 

A pornographic, antonymous pun on "Error 404". It suggests, much unlike Error 404, that if you can think of it, that there is porn for it.

Person 1: Dude, wtf. Why would you even think of a santa-midget toe-fucking a hippo with his tounge?

Person 2: I didn't think of it... it already exists; Rule 404.

Rule 16

Rule 16 states that "No boner shall go flaccid without proper ejaculation." This means that a boner must reach ejaculation by means of vaginal, oral, anal sex or by masturbation before it is aloud to return to a flaccid state. Rule 16 applies at anytime of day, in any location or situation. Unorthodox methods of ejaculation are encouraged.

Mike: Jon has a boner! I see it in his sweat pants!

Jon: Damn. (Jon applies Rule 16 and pulls out his dick and jerks off)

Rule of thumb 

Originating from the Middle East, this refers to a father trying to penetrate his daughter with his thumb in order to assess whether she is ready to be married off. If penetration is impossible then she is not ready for marriage.

As a rule of thumb, Samira thought her father was somewhat unpredictable.
