Just as a brown noser kisses ass for favors, a pink noser kisses clit for favors.

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.

When a person is such a kiss ass they go beyond brown nosing and move their nose to the vagina instead.

A person that kisses up to a woman, especially on the internet, exceedingly. It's one thing to treat them well, it's another thing to be outrageous about it. Pinknoser is the female equivalent of a brown nosing.
