A mathematical concept. The ratio of available flathead screwdrivers to available Phillips screwdrivers when only a Phillips will do. A big number.
Can also be used to describe the ratio of flathead screwdrivers to flathead screws in the universe. Still a big number.
Also, apparently, the amount of reputation points you will lose for creating a node called The Flathead Number. *Still* a big number.
