A sock normally kept in the bedroom under ones bed, for the purpose of 'spunking' in to after having 'a wank'. A genuine spunksock can go unwashed for up to twelve months and hold up to four pints of jism. The original spunksock is a white sports sock with a red band and a green band around the top.
I've just put my spunk sock in the washing machine on a boilwash - it took me thirty minutes to unstick it from my bedroom carpet.
