"Kerr" is an up and coming gang, starting in the New York City area that is anti-illuminati. There are certain levels of what type of kerr you can be, and can be changed at any time through "demotions". You can recognize people in this group by their random shouts of kerr kur and their "kerr" conversations, which are very recognizable.
Nice guy when he is on his own. However when you find him with a group of "popular people he turns into a really bad guy that mistreats his friends and does everything he can for recognition and approval from "popular" people
Kerr usually describes a beast or a brick wall who is a complete tank. If anyone would of run into Kerr they would of been paralyzed with a bit of brain damage and have to eat out of a sippy cup for the rest of their lives
