a tosser is similar to a wanker, well, its really exactly the same. tossing and wanking are both different words for masterbation. if you dont know what any of those words mean, dont use them.
as above but more like wanker than dickhead, as the toss in tosser refers to the tossing motion of masterbation (or tossing-off). A tosser is someone who masterbates.
