Sheikh, or Sheik, is Arabic for Chief, with all the hilarious connotations the word has in English.
A Sheikh is someone who thinks they are really big and important and likes telling other people what to do, but who is really just annoying.
Everyone else at best humours them, and at worst tells the truth in their face. But because they are oblivious to the fact that nobody cares, they continue trying to be bossy all the same.
example of usage, "Why do have a beard, are you a Sheikh?"
