ok, here's the true explanation:

while the word wanker is a more general and term for expressing disdain for somebody, the word tosser describes a person with a tendency to show off or brag in an excessive and embarrassing way.

or someone whose explanation of a word consists solely of another synonym.
"well at first i thought this guy delivers, but in the end he was just another tosser."

A asks: hey, what does tosser mean?
B answers: duh, it means: wanker.
A thinks: what a tosser.
B thinks: damn, i'm smart...

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.
