unfartable 

A time when it is rude or untimely to fart yet one has to.

He was on a date with a hot chick and knew if he farted he would ruin it, so he decided it was an unfartable time.

Taking sluttiness to the next level.

Misha thought she was at the peak of slut culture with her fake fur, fishnets, and platforms, until Brittany uptarted her with a "slam it" tramp stamp tattoo across her lower back.
