Shirt Air 

The act of pulling your shirt up over your nose to make use of the reserve of air in your shirt that doesn't stink. Usually done when no one else is there to ridicule you for being a wuss.

Dude, someone dropped a deuce in the mensroom that was so bad I had to switch to shirt air.

Hah, Jim is such a girl, someone farts and he instantly switches to shirt air.

Shit Flavored Air 

An unexpectantly raunchy patch of foul smelling air caused by a nasty fart. A delicacy in the right setting- see dutch oven. Usually the culprit is unknown (see SBD) and most often it is caused by random crop dusting.

Scott- "Did you taste that?"
Tap- "I smelt it."
Scott- "Shit flavored air!"
