A very annoying, itchy feeling that one gets when they don't wipe their ass properly/completely. Sometimes you can wipe until there's no shit left but still suffer from this condition. Oftentimes this condition comes involuntarily and is not usually a result of lacking anal hygiene.

One way to counter-act this feeling is wiping with a wet cloth.
I had explosive diarrhea earlier today and it was impossible to wipe. I thought I got it all but the itchy sensation in my crack foretold of my incoming crusty ass.

It’s an acronym standing for Can’t Remember A Fucking Thing. It’s usually used to describe embarrassment at being unable to remember someone (CRAFT moment); going onstage as the lead in the latest theatrical performance and your mind goes completely blank (CRAFT situation); the next morning after a night when you got pissed as a fart and woke up in bed cuddling a traffic cone and a string of fairy lights wound round your prick.
“Where did you go after we left the pub?”
Dunno, CRAFT.”
