I'm still not convinced it was a real bet so it was less me winning than you losing:)<quoted text>
I knew that. You should know that I google everything. You should also know that I like having fun with urban dictionary. I was surprised nothing showed up there. And, waving your fingers is an optional enhancement for cocking a snook. Typically, you don't wave them unless you won a $50 dollar bet.(cocking a snook at you).
Since TUD is a wiki-like reference, why don't you submit your definition and become the first on your block to mock the British. I have a feeling time is of the essence since GB will be an Islamic country soon and cocking snooks will probably be declared haram.
