purple stuff

A drink alternative offered in lieu of Sunny Delight. Nobody really knows quite what it tastes like because of how often it is overlooked. It resides in the back of the refrigerator and is usually offered as part of a long list of other beverages that will always end with Sunny D, whereupon all those present get excited and invariably choose the Sunny D.

Only one person is ever documented drinking the purple stuff. He was a little fat kid with glasses wearing a "No Fear" shirt. All of the more althetic kids got in front of him a drank the entire bottle of Sunny D. He was left with the purple stuff. He drank some... and was never seen again.

stuff you

Referring to the first, yes it is derived from STFU which means "shut the fuck up" Stuff you is a tamer version more widely accepted, yet still holds the same message of shutting up.

dude: hey why dont you see me some time?
