Agreed. I think the urine theory comes from the mistaken fact that trace amounts of ammonia will have the same effect that vinegar does (vinegar has been shown to inhibit unfired nematoctyes from triggering in SOME species). Unfortunately, freshwater, which urine is mostly, has also been shown to cause nematocytes to fire. That being said, nematocytes are not all created equal and I have heard anecdotal evidence (no literature that I have seen) that vinegar has the opposite effect on stings from some non-jellyfish species such as the Man-o-war (read excruciating pain if applied). So, no idea how coral would react.

We used to use vinegar and lidocaine when I was diving in the tropics. I have also heard that meat tenderizer breaks town the proteins in the toxin...'cause everyone carries that in their beach bag.
