Dude, look at that 80 rogue over there, killing all those lowbies in Tarren Mill. He is such a gankster.

An uncommon spelling for the word "gangster." This term is usually aimed towards the ghetto scene as a positive adjective. It usually compliments language, music and clothing but is not limited to just that.
