Wanker literally means" "one who wanks"(masturbates). It is normally intended as a general insult rather than as an accusation. Wanker has similar meanings and overtones to American pejoratives like "jerk",[1] "jerk-off", and "prick". One particular connotation is of someone self-obsessed or a show-off (usually male).[2]
