A mixture of "douche bag" and "dick head", for when you want to call someone both but cant decide between one.

A casual invitation / threat used by an individual that is not afraid of fucking someone up.

When I was a student, my housemates who were identical twins used to call each other "dick head" in between smoking joints/drinking beer.

I decided to make things far more civilized by appointing one "dish head" and another "pan face".

Seems fair.

Then in Uncharted 3, you had to beat armored enemies who I would call either "pan faces" or " dish heads".

Such symmetry.
