The U.K. equivalent of the U.S. noun "jerk", in that they both originated in calling someone a masturbator but have long since evolved into a general way of describing one as an unintelligent, nasty fool. "Wanker" most often means dolt or moron whereas "jerk" more often implies malevolence.
a sensation experienced when having a wank but you are disturbed by someone openning the door etc and you must turn around or pull your pants up very quickly.
I was having a wank yesterday when my mum was out but she came home early and I got wankers whiplash
Someone who washes their penis on the urinal flush stream. To do this, they normally thrust their pelvis (and thus penis) deep into the urinal, until the penis touches the stream. They will then flush the urinal, often repeatedly, until they deem their penis to be clean. Paper towel is then used to dry the penis.
One variant is to just use a paper towel (available in most public washrooms) run the paper towel under the urinal stream, and then wash the penis manually with the paper towel.
That guy is a "wanker washer". I saw him washing his wanker in the urinal yesterday.
Large bore exhaust pipe attached to Vauxhaul Novas/Astras by Chavs in the misinterpreted impression that it will make these shitty motors go faster. So called because you have to be a wanker to want to attach one.
