(v) to [sneer] at -
When your junk (not mine) get so cold that the balls all but vanish and your shaft retracts so far inside that pretty much all thats left poking out of your body is the head of your dick.
This causes all your foreskin (assuming you havent been mutilated - and dont argue; that is what it is) to bunch up and jut down at a right angle to your dick.
This unfortunate mess of nature, combined with your [cockburns] as the hair, creates a pretty accurate rendition of [Cyril]/[Cedric Sneer] from the cartoon The Racoons. Thus your junk is sneering at you/passersby.
Effectively shrinkage but with ample foreskin. Can also be caused by playing sport or sometimes just whenever the fuck it likes.
