Oh, I don't think it comes from the other word...I think it has a meaning that means a man of fairly low reputation who essentially sells his services to older women...a concept that young girls innocently do not need to be singing about. I think that in a case like this adults can step in and say you have to not say that word..here is one you can substitute..as has happened in the case of many counting games, sea shanties etc....I personally if I had daughters would not let them sing that in my presence...even if there are couple of ways to pronounce it...I know my Irish roots are showing...but a whole lot of effort went into making me repressed and some of it is paying off...mg
