Chavs are hilarious. And they look like fools. I just read about it here
http://en.wikipedia.org/wiki/Chav
"The accepted etymology for "chav" is that it derives from the Romani word "chavi", meaning a child.[4] Related words derived from the same source include "charva" meaning prostitute (used in north-east England in a similar sense). In modern Spanish "chaval" or "chavo" means "lad" (eg: El Chavo, a Mexican television comedy whose principal character is a street orphan).[5]"
