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.
"You just don't understand me!!! I won't do my Homeworrrrkkkk!!!!"
