Term my grandmother used to refer to farts that have been both squashed and amplified by sitting in a leather reclinign chair during the release.

a bad fart

The toll for riding in anothers vehicle. Only one is required in trade.

The most acceptable forms of payment for the favor of being given a ride to any destination. Roughly translates to: money, weed, or sex (oral sex is also acceptable). Gifts should be given promptly and without hesitation.

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!)

the worst smelling fart know to man that burns your ass hole
