The term is slang, used heavily in the South. It means you have a millon things to do and you are moving fast to get those things finished.
"This cute, little, blonde, girl I know, way down South, talk's 90 to nothing, drives 90 to nothing, and is 90 to nothing at everything...and I mean everything...unless she's asleep, then I imagine she dreams 90 to nothing!"

Get the 90 to nothing mug.
Typically a "Southern" term that can be used to express something that it is a sure thing. That more than likely, it will happen again.
I'll bet you 90 to nothing that girl learning to water ski is gunna fall on her butt and flip her bikini top off again!
