1. (adj) Modern day equivalent of the 80s adjective fresh. Used to describe something that is regarded highly, of the best quality, or simply considered good/cool.
Usage is derived from the name of the well known feminine santitary rinse "Massengill Disposable Douche", which was promoted heavily in various TV commercials for its ability to keep its users feeling fresh and clean.
Refers to all men who act like "douche bags" or dress like them. They normally travel in packs and can be easily spotted by their shiny and/or striped shirts. Must possess an arrogant attitude with nothing to back it up.
Linda is such a flexible container of Massengill that it ain't even funny!!!
She did the most unfeminine thing in the world and plugged up all of the shitbowls at the rest stop with paper towels!
