Shred face 

The unintentional weird and often humorous face(s) one makes whilst engaging in a mentally strenuous activity. Most often used in reference to the face a guitarist makes while "shredding".

Dude, your shred face is hilarious. You look you're trying to mouth words and your bottom lip keeps twitching. Do you need to blink that much?
