Phrase meaning

Can anybody tell me what this means,? MAKE A BULLFROG BALL A JACK. or is it self-expanatory?

I would guess that it means something extremely provocative. It sounds like a line from a song (sung by Jerry Lee Lewis) called "Big-Legged Woman." The line is, "Big-legged woman, keep your dresses down. You've got something up there baby that would make a bulldog hug a hound..." Or words to that effect.
