Where the women roll and make thunder

The story:

I have an older brother and a younger brother, and we often had fun with what we KNEW were misheard lyrics (like with Blinded by the Light). But this was back before internet access and we didn't know the real lyrics to this song. We'd heard the expression "Thunder Thighs" before, so this was the best translation we could come up with. I'm not sure I can pinpoint an exact moment when we realized that we were saying it wrong. I think I might have been about 8 or so when my older sister laughed at us. She had been a subscriber to Song Hits magazine, so she knew the real lyrics. Being the mean older sister that she was, she primarily picked on me (being the cute little sister), and enjoyed telling her friends about it, even years after the fact. To this day, whenever I hear the song, I still want to say "our" lyrics instead -- and to be honest, I still think they're much better than the original; AND any other mis-translation I've heard.
