Stretcho

A word used to describe someone who is profoundly stupid. A type of stupidity that is an insult to intelligence itself. Politically correct people would like you to be rude to someone in a less offensive way, perhaps by calling them dumb instead. This ignores the fact that dumb, idiot, and many other similar insults used today were all old-timey technical terms for retards. It also ignores the fact that any word used to describe someone of below average ability in any area is an insult to someone with average ability or higher in that area.
