A slang term used to define the most bad ass of people in a certain group, or social gathering. The word gets it's meaning from a polish kid who set his school on fire and when asked why he did it, he just looked at the authorities and said, "cause i don't give a fuck"
whos the kid showing his junk to the teacher? Oh thats just Bob, hes the Graska of our school.
