The rule of 3 states how men overstate and women understate their number of sexual partners.

When asking someone about the number of sexual partners they've had, multiply a woman's answer by 3, because a woman wouldn't want to seem like a slut. When a man answers, divide the number he gives by 3, because he wants to seem like a player.
Josh said he'd made it with 3 women this year? Rule of 3: that really means he made it with one, or zero.

Always try to occupy odd-numbered urinals. Never occupy a urinal right next to another urinal currently in use. And never, EVER start a conversation with anyone if you are using a urinal and/or if the person you want to talk to is using a urinal. That would just make everything really awkward.
*Guy 1 enters bathroom, occupies urinal*
Guy 1: Hey bro, what's up?
Guy 2: WHOA WHOA WHOA MAN! RULE 1-3-5!
Guy 1: Oh shit, sorry
*Guy 1 moves urinals, pissing commences in silence*
