Did I really just do that?

How do I get out of this one? I don't think I can... It sure is making me laugh, though! One of my precious daughters walks in and says "Mom, friend's name (all privacy is protected here on this blog... most of the time!) just called another friend (see previous parenthesis) a bad word and I don't know what it means. I think it was something like BH or VH or something. What is it?" Now, let me interject right here that on a somewhat-regular basis, I have a cuss word inventory with my kids. They get to tell me all the words they aren't supposed to say (so I can see what the schools are teaching my children, you know, the real life education they get while getting an education?) and I tell them the literal meaning. So far, it has kept my kids from cussing or using inappropriate language, because the meanings of the words are so silly and you can get your meaning across without demeaning yourself by using cuss words. At least, I hope it has worked so far. And, I love hearing what words my kids think are cusses. (stupid, looser, heck, and yes, the four letter ones...) Ok, back to the story...
So I, the mom, the wise one, reply "Did she say the word b**ch? Is that what she said?" Child answers, "I'm really not sure. But what is that word mommy? Is it a bad word? What does it mean?" I'm too busy storming out of the house to answer. I might have said, yes it is a bad word, but I really don't remember... I go outside and holler across the yard "Child! Have you been calling someone a bad word?! We don't use bad words at THIS house!" She then explains to me that she didn't say a bad word, she said the initials BH which stands for Butthead. But, no she wouldn't say a bad word over here. She knows not to. At this point, I am very proud of myself. I do not double over laughing. I contain my composure and remind her that I would appreciate it if they talk nicely about other people. She says "Yes Ma'am" as sweetly as can be. At this point I start yelling at everyone to get in the car, cause we're goin' to church! Which is where I need to be to confess my sin of teaching my child how to cuss.
