The proper way to squat. Only girls and phaggots complain about this and if you think it kills your knees your just a pussy. Basically you go further pass parallel tell your ass is almost touching the ground ("grass"). This ensures you properly work all the muscles. And it looks way more bad ass. 225 ass to the grass or bust. Also known as ATG
Bob: *quarter squatting 225*

Frank: hey bob why don't you stop being a pussy and start squating ass to the grass *squats 315 ATG for ten reps*

If someone is asking you for a ride and you don´t feel the need to give it away for nothing, it´s a good opportunity to ask for "ass, gas or grass".

Meaning you wish to take advantage of the situation by getting a good fuck, some bucks for the gas you´re gonna need or at least something to get a buzz from.

(Maybe one of you might describe it better, as I´m by no means a native speaker!)
