Dang’s Law

As long as your girlfriend is the last person you’ve slept with you haven’t cheated.

Person 1: Mate didn’t you sleep with Sarah?

Person 2: Yeah but I slept with my girlfriend today so according to Dang’s law I haven’t cheated.

veselekov's zeroth law

A scientific law explicitly stating that all members of the female race shall be unable to be sexually attracted to any man who has full autonomous control of their eyebrows. This does not hold true for any relationship that remains at a platonic level, such as friendships, or even jogging buddies. Predates his first law of gas, grass, or ass: no one rides for free

Player 1: Man, that dude's eyebrows are going everywhere! he's even doing the wave!

Player 2: He probably suffers from veselekov's zeroth law
