Metal Face

The term refers to the the phenomenon of one's face muscles inexplicably contorting upon hearing an extremely metal riff. It is uncontrolable, many have researched it but it remains a mystery. Why do heavy ass riffs make us do this? we'll never know. Also, those who make and/or play the riffs cannot help it either, and are forced to do the metal face as well.

To do the Nu-Metal Face:
1) PLace your clenched fists against the sides of your head, pressing in on your temples.
2) Contort your mouth and eyes in the way that you might if you were passing a really big shit
3) Rock back and forth slightly.
4) Scream "Noooo! I won't tidy my rooooom!!!" at the top of your pre-pubescent voice.
5) Repeat as necessary, occasionally pulling up the top of your Linkin Park hoodie for effect.
