7.
A person that not only lives but aspires to live the main stream life. This includes a boring job done without passion, 2.4 children, an SUV and a house in the burbs. They just go along living out their lives as a backdrop to history and a study in the mundane. Originally coined from the industrious characters from Fraggle Rock that just went about their business mostly oblivious to the goings on around them.

a device used for defrauding vending machines. a dollar bill or other small denomination bill and two pieces of clear packing tape about 10" long are required. the doozer is assembled by creating a dollar bill with a tape "handle" such that the doozer can be fed into a vending machine and then removed by quickly pulling the doozer back through the rollers. if done properly the machine credits the user for inserting the bill and the user now gets a free snack and change from the $1.
"yo, let's go down to the student center and use the doozer to get free cheetos"

n. An impressively large shit. Usually one where the subject's legs fall alseep from sitting on the toilet for too long. There must be atleast three courtesy flushes performed before a doozer can be official. Taking a picture with your cell phone of the doozer and sending it to your friends is optional. A doozer should be graded by any who witness it.
Yo, Booth man, I just dropped a nasty doozer. Come take a whif of this.
