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.
Example:
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!
