a word said in a high pitched, annoying voice when passing bye a stranger in the supermarket to see his or her reaction. Basically, just a way to mess with people. Usually accompanied by a quick flashing of the palm with the elbow bent at 90 degrees.

George: Hi!

Stranger Tim: Wull hullo there, fella...(wtf?)
