dumby 

Common misspelling of the word dummy, almost always used by the people who can easily be described by the word itself. Just because dumb has a "b" at the end, does not mean dummy has to. Also, dummy does not rhyme with Gumby.

"You are such a dumby!" -Lauren, Monica, etc...
"Actually, you are the dummy!" -Brandon
