Wanker

A Male who masturbates. Usually used as an insult, i mean its not like we all do it or anything, well besides that for some reason we get the right to make a joke out of it. in my opinion it is probably that person compensating because their ding dong is a bit shorter than a french fry.

"you fucking wanker"
"oi you wanker"
"fucking wanker"
"you are such a wanker"
