to call someone when you are in the mood to fuck and have phone sex.

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.

A synonym for phone sex.
I was listening to 'Telephone' by Lady Gaga, and it almost sounds like she is saying "Stop telephuckng me."
