Hasselfactor

1. Allowance made in any form of planning for the unexpected appearance of either David Hasselhof or one of his media products, be it some cheesy TV show about half-naked people or dreadful music.

2. Amusement taken from looking at the naked torso of an aging gent who has had bicep implants, but still has a slightly sagging chest.

Bert: Hey, let's go to the beach. I reckon we could make it there in less than twenty minutes.

Ernie: Don't forget to add on an hour for the hasselfactor of finding a parking space in amongst those fancy sports cars, artfully aged veedub busses, and big red lifesaver trucks.
