ass-dirt

The ring of dirt left around the toilet seat when a dirty ass person gets up off it.

Dude 1: "Man, can I use the bathroom at your house?"

Dude 2: "What's wrong with your bathroom?"

Dude 1: "I hate using it. My older brother always leaves ass-dirt on the seat."

Dude 2: "Awww... that's just gross."

10-til

A BMW 750. This is in contrast to the BMW 745, which is referred to as a quarter-to-eight

Ex. 1

News reporter: "You've just won the lottery, what are you going to do next?"

Deadbeat dad: "Yea, Imma buy 12 10-tils. One for ever one of my baby mommas."

Ex. 2

Business chick 1: "Girl, what you gonna do for 2008?"

Business chick 2: "Not much really. I'll probably trade in the quarter-to-eight and get the 10-til."
