1. A Wanker is a vulgar word used in Britain for masturbator, someone who excites their genitalia for sexual gratification, usually until orgasm.
This gives rise to the famous wanker hand signal used for making one’s feelings felt in tense traffic situations, consisting of sticking one’s hand out of the window and moving it up and down in a masturbatory fashion to show that the other driver is a wanker.
2. A Wanker is a person who refuses to fit in with a peer group and generally hinders the smooth running of affairs.
