Someone who tries to jerk you off under the table unbeknownst to you. (Thus to criticize the analysis given by the definition of anonymous on May 31 2004, the original sense might not have referred to self pleasuring, or a useless self-pleasuring fool at all, but rather makes reference to giving a less than pleasurable wank on someone else's knob. This is lost on most average wankers on the street today, who hear the overused term at too young an age, and then never can get past the giggle factor of picturing someone diddling on their own willy once they learn that simplistic meaning, never thereafter able to fathom the sordid depth of someone edging someone else who is captive against their will. ) A cheat of sorts. An unscrupulous or uncaring person. Slimy power player. "Prick" as opposed to a "Dick."
Bob told me how lucky I was to be dating Karen; then the wanker tried to make out with her at my party!
