the american verison of the british insult "lousy wanker". It is mainly used by douchebag creeps that want to appear cool to there friends (if any), but mainly just look gay.
Today, a fat creep at my school called me a lowsy wanker, becuase apperantly he didn't know how to spell "lousy wanker". That day everyone ay my school beat him up.
