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.
If it wasn't my grandmother, I would have told the supplier of the ass gas to drop dead in an effort to shut their asshole.

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!)
