F.I.F 

F.IF = Fart Induced Fit. The mad flailing of arms and nose pinching that happens as soon as a fart is smelt by the person unfortunate enough to be in the room when somebody else farts.

Hey man I did the best fart the other day but my girlfriend had a total F.I.F.

or, on seeing someone's reaction to your fart you can say
"Don't F.I.F out on me now!"
