The part of a vehicular on-ramp or off-ramp curve where people throw their trash out the window of the car because they think other drivers can't see them.
Most of the trash is empty beer bottles, fast food containers and empty energy drink bottles. Most of this is done by people who have no idea what a garbage can looks like and leave their shopping carts in an open parking space.
DRIVER: "Oh man, I can't get pulled over with all these Keystone Light cans under my seat".
PASSENGER: "Dude, don't worry, when we get off the highway to stop at that all night adult bookstore, lets throw them out on the blind curve on the off ramp".
DRIVER: "Good thinking! Hey! I just popped a boner, can two people fit into a peep booth?"
