An idiot with no common sense. Typically large oafs that speak mainly with one possibly two syllable words.
If you have seen the Godfather this will help. I'll put it in a sentence. That Luca Brasi is a real marmaluke.

A simple minded buffoon. Usually totally clueless. Very similar to a marmalukeexcept a little stupider and more fun to laugh at.
