Mul
Saying "Mul" whilst slapping your cheek indicates you think the person you are doing it to is an idiot.

You can also stick your tounge in your bottom lip so as to closely resemble a retarded person.

Mul comes from the extended phrase Katyulamulickiawi - which has its roots in Maori language of New Zealand.
