Chutney bum

When you haven't quite soiled yourself, but everytime you walk, you feel as though someone has spread chutney lightly on the inner garments of your underwear.

(Not to be confused with bum chutney.)

*Farts* "Uh oh"
Friend: "have you just farted and followed through?"
Victim: It might not be that severe. I think I've just got "chutney bum."
