Aquaman Rule 

As seen in sport and other pursuits, the setting and context of an action can mitigate or nullify entirely an unambiguously and unabashedly homoerotic act. Much as a pool full of Speedo clad men climbing over each other or a grassy field full of men in tight pants capriciously running about slapping each other on the ass can be excused under the thinly veiled guise of being water polo or baseball, claiming that the Aquaman rule is in effect (before, after or during) makes any act, no matter how ‘gay’, totally ‘chill’. The philosophical basis governing this that if you do any thing in the water it’s totally not gay because, you know, humans live on land.

“Hey did you guys ever notice how that one time I made out with a dude in the hot tub at the LXA house that it totally wasn’t gay because, you know, humans live on land… And like that’s the Aquaman rule, and it’s on Urban so its legit… and I’m totally into chicks?”

Rule Zero 

When you're trying to figure out whether doing something is a good idea or not, there are various rules that come in to play, such as Have Fun, Do No Harm, Have Fun (again), What Happens in Vegas, etc.

Rule Zero, the rule that always comes before all the others, the most important, basic rule of doing anything is: "Don't be on fire."

- I can't get this bbq to light.
- Here, use some petrol.
- I am not breaking Rule Zero to cook a burger.

--
- Hey, let's see what happens if I fill my foreskin with lighter fluid and light it.
- I am invoking Rule... wait... yeah, go ahead, that'll be funny.
