A play of words on "Creme de la creme" meaning "
Cream of the cream", this quite
literally means "Cream of
the shit", for use in describing the worst of the worst of the worst, as invented by a bored French Student one day.
"I'm going to drop all hell on Marketing, I need you to
find the "Creme de la
merde" of your
office to send over there, okay?"
