The
Australian slang version of the English "wanker".
Slight
difference in that wackers tend to be more boisterous than wankers. Wankers kind of like to do things sneakily, and probably harbour a fear that people are calling them wankers behind their backs.
Wackers, on the other hand, are oblivious to what people say about them and seem to even believe their own bullsh!t.
There are more
Australian wackers than wankers, but believe me - we do have both kinds.
