To dirty paint is to have a blank canvas i.e a very pale wench.

(Dirty painting is to try to make an improvement to an abomination of a woman which cant look any worse)

This act of dirty painting is when a fugly white girl is stripped down and have faecal matter from the artist rubbed all over the canvas. The artist may or may not choose to use a variation of bodily fluids for different colours. As in phlegm used for a green or a pale yellow, ear wax for orange, or spooge used for a white or a slimy texture. The dirty painting is only complete when the surface area of the wench is covered in exotic bodily fluids.

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.
