Jface 

it's the kind of face a person makes when someone says something utterly stupid, or when you drop something after you were trying so hard not to. It's like a "WHAT THE HELL" face.

You can also say it whenever something dumb happens. It's kind of like a "okay no" sort of face, you know? Everyone makes it a lot, they just never know it's a jface ;)

sort of like this: =_=

Person 1: I made up a new word today!
Person 2: Cool, what is it?
Person 1: Squinkle.
Person 2: ...jface.
