Covus is any nasty or disgusting substance that is so horrible that you would not place in your mouth. For example, the liquid that gathers at the bottom of a dumpster is covus. The stuff that builds up behind your toilet is covus.
Dude, I can't believe you put that covus in your mouth, that's nasty.
