She's a b**th---owwww

The story:

It was playing on the radio and I sang out "she's a b**th...owwww!" and my dad was all "what'd you say?" and I thought he was mad because I said b**th, but then he just started laughing and told me the real lyrics. I told him that he was stupid and wrong-why would he call her a brick house? that doesn't even make sense, I said. He explained the term, and I blushed and turned the radio up.
