Silly Billy
From Wikipedia, the free encyclopedia
Silly Billy is an epithet intended for mild abuse. It is often used to describe a person who has just done something of an idiotic nature or is in fact silly as a whole. The person being referred to as a "Silly Billy" is not necessarily named William.
Denis Healey, the British politician, was known for his use of the term "Silly Billy" as a catchphrase. This originated with Mike Yarwood's famous impression of him, although he later used it himself in parliament.
