As far as I'm aware tosser has nothing to do with mastubation but comes from an old sailing term for a drunken idiot - 'he's a toss pot' - ie someone who drinks a lot is a tosser or toss pot.

Get the Tossermug. A chiefly British derogatory term, literally meaning "one who masturbates," but properly used to describe anyone who is either incompetent, supercilious, or otherwise generally unpleasant. Tosser is a British synonym to the primarily American derogatory term, jerkoff, which is also used in the same manner as wanker and tosser.
Joe Sixpack: I'm going to need you to come in for work on Christmas Eve, Christmas Day, and New Year's, all without overtime pay.
Jolly Roger: Don't be such a tosser. I'm going to the pub with my mates on those days!
