fartcan 

Any muffler with a wider exhaust port that allows for a louder sound. Typically found on cars owned by drivers who can't afford a real street-racing car but want to act like they have one.

Fartcans are installed on cars strictly to make noise to annoy other drivers.

fartane rating

A number associated with the richness of flatulence. A number 2 rating is average and might be mistaken for "forgetting to take the garbage out" A number 4 rating will typically clear out a medium sized room while a number 8 is a serious combustion and explosion hazard.

Arthur, at any party could always be counted on to rip one with a number 4 fartane rating. People who knew him well would always reply with a blessed be the fruit right before they made their exit.
