When you are piss drunk and a) can't control your actions or b) can't control what complete bullshit comes out of your mouth. The next day you wake up and remember what you did or said and want to crawl under a rock and die. Rock Syndrome.

Referring to someone that has no intelligence. No common sense. Someone who is just dumb, as rocks have no intelligence.

Bob: (thinks to himself; "this dude is dumb as rocks.")

Can also be used to describe later bands such as Five Finger Death Punch and Bad Wolves. The nickname comes from the types of people who usually listen to this music, as well as the performers sometimes. Also referred to as butt rock.

The spot where the Mayflower landed, so named because the rock's shape somewhat resembled a Plymouth automobile. (Hey it must be true --- renowned historian Dave Barry said so himself! :P)
The whimsically-tasteful car-themed landscape (Cadillac Range/Tailfin Pass, Wheelwell Motel, Coolant-Filler-Cap Mesa, Hood-and-Fenders Bluffs, etc.) of Radiator Springs is hardly anything new --- almost 400 years ago, the Pilgrims named their original landing-point "Plymouth Rock" due to the rock's being shaped something like a Plymouth automobile.
