One of the more
negative forms of the word "slip" comes in the term "slipped
disc." A type of back injury that causes intense pain, the slipped
disc does not involve any slippage at all, according to The
Spinal Foundation. That leaves those of us who have never experienced
this injury to ponder why it is called this. It undoubtedly has something
to do with some guy slipping on a banana peel.
