Chinchinbeaver; To attack someone by karate chopping them twice with your hands held together as though praying (the chin part) and then poking them with the tips of your fingers whilst your hands are held in the same manner (the beaver part). This should be done whilst chanting Chinchinbeaver in a monotone voice. This is best administered by a group to one unsuspecting victim... preferably whilst they're stoned.
Guy 1 - Dude, let's go and Chinchinbeaver Ryan, he's so caned.
Guy 2 - Yeah, he hates it!
When one crimps off a turd prematurely and is left with it partially stuck up your bum.
I had to rush off the toilet the other day and was left with the worst hanging Chod!
