Edgy is when little kids try to act/look mainstream/cool in public but end up looking like little annoying shits.
"See that kid over there? With the backwards cap and sunglasses? Jeez, he thinks he's so edgy."
They typically gel their hair to the side, and always have some sort of "practice". They wear usually black name brand shoe clothing and say things like "You haven't done _____, that's sad!" or "Oh my gosh so DUMB!". Edgy balls can be exceptional complainers at times. They go hand in hand with Ball and Emo.
That Isiah is sure an Edgy Ball! He expects me to let him copy my homework when he does not let me copy his?
