runoff 

The leftover urine that drips onto the pants or shorts after zipping up, giving the impression that one has pissed himself, or the water from a faucet that somehow ends up on said parts. Runoff is commonly hidden or removed by wearing long shirts or utilizing the hand-dryer while no one is around.

Bill: Oh hey man looks like you just pissed your pants!

Sven: F*** runoff!

Hipster Runoff 

Probably one of the best blogs on the internet, because it's a bunch of hipster hating hipsters, and they're cool because they can take a little joke about themselves,

Made by Carles, but no one really knows who Carles is, a girl or a guy, old or young, etc. We don't know.

Hey did you hear about how Best Coast insulted Hipster Runoff ?

runor 

An extraordinary blunt, cute and sexy fellow who abides by his rules.

Runor can be defined as a womanizer

He is an intelligent but lazy fellow bold and mindful of his business, rich and well known of his simplicity

He's simple, just as a runor should be

Boner Runoff 

The water that drips off your boner when you're taking a shower.

I held the boner runoff in my hands but it just slipped through.
