:'It seems to me they're just humorous ways of saying "fuck all"' Well, that's were you are quite wrong. It's a humorous way of saying 'just a little bit'. So we say "it's a bee's dick too big" or "move it left a poofteenth". I don't think it's any less valid than "realtors throw", which might be common in the US but is unheard of here (Australia) - and as far as I can tell is only a humorous way of saying "further than you might be led to believe". So, my vote is that if "realtor's throw", stays then so do bee's dick and poofteenth. ;)
