I knew Slew Foot Sue as a jump-rope and clapping rhyme - it was very popular at my elementary school. This was in Gulf Coast Texas in the 1990s. I think one of my friends learned it at summer camp and taught it to us. The objective was to sing it as loud and fast as possible:

There was a girl, that, I once knew
By the name, of, Slew Food Sue
She, had, a shirt-tail factory
Down by the riverside (riverside, riverside...)
She had a face, that's, all she had
She had the body of a softshell, softshell crab
She was standin' in the middle of the shirt-tail factory
Man that girl was fat! WHOO!

We'd always clap, smack the jump-rope, or bang a lunch tray on the table to emphasize the "WHOO!"
