Sorry LFL. You're not sorry you wanker. I don't mean to be a wanker, whatever the heck that is. Well, I believe to wank means to masturbate. So basically it is calling someone a jerk-off I believe. Now in the 80's when it was the height of hairmetal bands and such, my friends and I used to call them "wankers", basically metal heads. This also relates I believe to the awesome movie Spinal Tap where they were calling each other Wankers as well. So there you have it.
