Wit washing is the act of utterly destroying an opponent with a single weapon of wit. Usually occurs when an intelligent and modest person is provoked by an ignorant asshole.
Note: Not to be confused with unoriginal, snarky remarks. Shit like that will land you in the asshole category. Ex: That's What She Said, Your Mom etc.
