Nonce

This is from UK Slang, and it means "Not of Normal Criminal element", a paedophile just so you know, a lot of English people use it and sometimes say it to their mates. You don't really want to be called it, so yeah, just watch out :)

"Person 1: That Jimmy Saville bloke was a right nonce, disgusting man"
"Person 2: He was!"
