silly billy 

An proclaimation of victory used by someone at least 25 years older than their opponent. It is such a bad insult, that only the older (or should I say wiser? Maybe not...) can use it and not look stupid. It basically means that their opponent is too immature to be treated to a real insult.

Silly Billy, don't fuck wit dees old ass niggaz.
