The annoying practice of begging people for something, usually money. Usually when someone scabs they will repeatedly ask a passer by (especally someone they know by name) for the thing they are after until they give in.

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.

Furiously masturbating for prolonged periods of time. The penis skin may be so traumatized that scabs begin to form.
