Squirrel sock

The art of inserting your penis into a dead squirrel and then proceeding to rub it's sides rhythmically or masturbate as if you were having a 'posh wank' untill you eventually ejaculate and your semen dribbles out of it's ass hole.

P.S. it may also help to break the squirrels neck if you, unlike bare hench mase, have a large penis...
