snitchface
the face of someone who ratted someone else out and got caught.
snitchfaces display darting eyes, sweaty brow, quivering lips, and various facial tics.
After Congressman Reichart ratted out the bus driver that gave him the finger, he displayed his snitchface to the public for the whole world to see.
