Dumbface 

Dumbface is a phenomenon that is like the were-wolf situation.

It happens to someone when they do or say something dumb that is so explicitly dumb that the dumbness begins shaping one's face into a dumbface.

Unfortunately, we have yet to find a cure but one day, this illness will be eradicated.

"Bro, I think Ethan caught the Dumbface."

"Oh sh**, run!"
