What is the punk/rock/alt song featured in a current (Dec 2007) MTV commercial?

Question

Here's as much as I know...

One guy is on stage singing the same line over and over really intensely.

Crowd is going crazy in the background.

He is almost yelling so it's difficult to understand the lyrics but I think the repeated line MAY start with "Your Mother..."

Answer 1

I gave up on MTV when they stopped playing music.
