A competition of insults, usually between two people and judged or observed by a group of others. Unique to the D.C. area, see also jone.
A competition where two people insult each other continously; the first person to back down, hesitate etc is the loser.
The usual insults revolve around physical flaws (look at yaw teeth, dey so yellow i don' needa put a light on at night) and clothing (yo, man, what make yaw sneakers?)
Thought to have started in Washington D.C. but there are variations all over the world, a particularly famous concentration being among young black people in London.
