A come back when someone is being exceptionally stupid.

This is a short form for "a slight case of the downs" implying that they have a mental disability but not a severe one. Typically this is defined when someone is caught being completely weird by themselves, being a little bit too clumsy or doing something without thinking at all !

Someone who has a slight case can also graduate to a "Full Case"at any moment without warning ! be alert
