Creeping Crud 

A close relative of "you don't know where that's been." Creeping crud is when you don't know what invisible germs and dirt is on a surface and you try not to touch it. The term can also be used to describe an unidentifiable substance, or to describe crud that is, in fact, creeping.

Ex. 1

Ben: Good thinking!

Ex. 2
Keith: What the hell is that?
Ben: Ah, just some creeping crud.
Keith: Right, better steer clear of that shit.

Ex. 3
Keith: OH MY GOD THE CRUD IS CREEPING.
Ben: WHAT KIND OF CANCEROUS THINGS ARE LIVING HERE?!
Keith: RUN, BEFORE THEY MUTATE EVEN MORE!!!

The Crud 

A name for the depression you feel after making a large monetary purchase. Often associated with anxiety and regret, even if there was initial excitement and joy leading up to and immediately following the purchase.

You just bought a new car or a flat screen TV... or you just returned from an exensive vacation. "My new TV is awesome, but I still have the crud from buying it." or "Today's my first day back at work after our trip to the South of France. Man have I got the vacation crud."
