[tuck rule] 

When you have a massive boner in a very uncomfortable situation and your erection needs to be tucked into your waist line pointing up to your stomach to conceal it.

Mark's teacher asked him to write on the black board so he had to apply the tuck rule to hide his boner from the whole class.

Hector was flogging the dolphin to soft core porn when his doorbell rang. Girl scouts were selling cookies.. he had to apply the tuck rule so they didn't think he was a diddler.

Ten Percent Rule

You must be 10% smarter than the equipment you are trying to operate.

Person #1: "Will you call maintenance and get the key? I've been pushing on this door for 5 minutes, and it is definitely locked!"
Person #2: Pulls door open and walks through, saying "Ten percent rule."

pure heart rule 

When an action or question, usually directed towards a significant other, is done with the best intentions, there is little for which the one bringing forth the question can be faulted (in theory).

If I bring up how I don't like that my SO follows his ex on Instagram to him with the pure heart rule, I should be fine.

In the event of damage caused to smoking devices, especially glass, (Bongs, Pipes, Bubblers, Steamrollers, etc.), The damager must pay for a new smoking device, and the first weed put into that smoking device.

Man 2: Rule 25, shitlick.

Asshole: Fuck.

Ja Rule 

A rapper who used to be good. Once put into mainstream America became a pop star.

Some one who acts hood, then pop, then when confronted about that, turns hood again.

Ja rule has lost his respect from the hood.
