When your wife, or any other woman, enters a room in such a miserable mood, that she could suck the fun out playing black jack at a casino strip club with your midget best friend.
Somebody give the fun bear some fucking honey before she ruins the party!
When you are clean but not presentable for the public. I.e. Hair and teeth not brushed. Face not washed. You are not quite scummy.
I can't go in the store, I'm skubby.
