trailer park rock 

sub-set of rock music that is really crappy and stale and extremely popular with the 13 year old trailer park rockers you see at wal-mart. Examples: Nickelback, Linkin Park, Limp Bizkit, Staind, Creed

I can't listen to the alt-rock stations anymore cause all they play is that shitty trailer park rock.

Trailer Park rock fight 

A fight amongst children (and some adults) in a "mobile community" using rocks to settle disputes.

Little Ray Jr. Said my momma was a lot lizard so I challenged him to a trailer park rock fight.
