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.

unfappable

Something so sexually undesirable, abhorrent or repulsive that it cannot be used for masturbation purposes.

Opposite of fappable.

Guy #1: Did you see "About Schmidt"?
Guy #2: Jack Nicholson and Kathy Bates? Jacuzzi? That shit was unfappable.

uncortable 

Same definition as the word “uncomfortable”.

Nurse, I’m uncortable can you please reposition me.

Elaine thought jun misspelt the word “uncomfortable” but little does she know, uncortable is the shortcut version and means exactly the same thing; only if written on paper in a hospital bathroom door.
