creeping crud 

military slang for highly contagious virii such as colds, stomach bugs, etc. that leave a person with any debilitating combination of non-stop runny nose, coughing up heavy phlegm, vomiting, diarrhea, extreme muscle weakness/pain, etc. The "creeping" part refers to the fact that it seems to make its way through ALL of the ranks eventually.

It's cold and flu season now, so if you get the Creeping Crud - go on sickcall and make sure doc gives you Quarters, because the rest of us don't want it!

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
Keith: Ben, I wouldn't take your shoes off in this smelly locker room; there could be some creeping crud in here.
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 creeping crude 

A cluster of spreading, oozing, weepy sores that
migrate on skin. The sores are red with yellow
crusts. Thought to be spread by poor hygiene.
It was 1956 in Florida that I first heard this term.
