aron.

They're orcs that you leave in the wash for too long with too much bleach.

Incorrect, my orc is white, but not whitewash. Do not be one, we will kill you.

Orcs that act or try to act like pinkies(The other races.) Pretty much every time theres a whitewash its because they are weak, a wussy, or have dishonored themselves in some way, which gets them kicked out, then they reject the teachings of Krug making them weaker.
