fart

One phrase that a lot of folks use but almost always misquote is "I couldn't care less".
Most everyone deletes the shortened "NOT" from it saying "I could care less".
Also, does anyone know where a "fart in a skillet" came from??
It denotes someone who is too active and hard to catch.

The fart probably emerged from a rectum, they ususally do.
I don't know where you got the skillet from - probably a cookshop.
