The act of making an atypical face especially while playing Guitar Hero. The look typically resembles a look of intense pain, wonderful bliss or sometimes even just plain jaw-dropping awe especially when playing "Through the Fire and Flames" on the Expert setting.
Billy: Look at that guy over. So shocked. So down. So glum...

Jason: Yeah. He must have just gotten dumped by his girlfriend. The guitar face says it all.
