Drool-Proof Paper

n. Documentation that has been obsessively dumbed down, to the point where only a cretin could bear to read it, is said to have succumbed to the 'drool-proof paper syndrome' or to have been 'written on drool-proof paper'.

For example, this is an actual quote from Apple's LaserWriter manual:

"Do not expose your LaserWriter to open fire or flame."
