Let your mamma build 'cause it's in my soul.

The story:

Well, I never really knew until I looked at this page. I really like that song and it was always the only lyric I couldn't figure out (I mean, what the heck would "let your mamma build 'cause it's in my soul" MEAN?) so I always just sing that part of the song really quietly. Until now, when I found out the real lyrics. I still think my version sounds better, though. More creative if nothing else!
