Similar to a wet willy, a wet rufus is when you put the juices from a womans vagina on your finger and stick it in her ear.

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.

Similiar to a wet willy, you take your finger, stick it in your mouth, then shove it up someones rear and swirl it around a few times. Then shout: "WET RUFUS!"
