Being suddenly wary of having referred to the recently deceased as a "bitch"
You're at the funeral of a woman you didn't much like. In fact, she was a real turd and you know it. Perhaps she was the nun who slapped your hands with a ruler when you were in Catholic school. As you walk past the casket you mumble to yourself "I'm glad you're dead, you old bitch" and you are. But suddenly you notice that people are looking at you. You may have said that a little too loudly. Or maybe they can just read lips, you really can't be sure. In that moment when you realize something may be amiss, you are officially old bitch you wary.
