look up any word, like blumpkin:
A stray sock often found beneath the bed of a teenage boy with a strangely stiffened texture used primarily as a recepticle for masturbatory ejaculate . Use has possibly increased due to current concerns for the environment as the item is reusable unlike tissues .
Mum - Johnny , I must try another brand of fabric condition as I had to boil wash the sock i found under your bed as it was so stiff !

Johnny - ...Erm...gumph!...swamp sock
