Ditto on what everyone else said. My mom likes to use the term banana boats when making fun of people with big feet, but that could just be her. We don't really have a derogatory foot term, sadly. Mostly it's just derisively using inventive words to make fun of how badly someone's feet smell. Sorry I couldn't help more!

I literally just read something, though, that ill mention. :) we don't say someone's in hospital. We say they're in THE hospital. Yep, that's about the only wisdom I can provide today. Good luck with your fix! (And feet issues!)
