OK, at this point I really need to explain what on earth is going on here:
"what does "pants" refer to?" - pants refers to trousers and pants refers to underpants and of course pants refers to pants as a noun. Pants also refers to heavy breathing as a verb.
I have absolutely no idea how we ended up with this situation, where pant(s) is a noun and a verb and really odd. I'm going to blame Britain, US and Italy (via Latin) and not necessarily in that order.
"A dog pants when they are hot but they only pant when they are hot."
Note how I end up slapping an extra s in for no apparent reason - actually, it is when I don't put a verb in front of that word. So: "a dog will pant" ... "a dog pants". The extra s on the word seems to make it a verballish thing.
On the bright side this is why phishing emails always look a bit wank.

Because (in English) adding -s(/-es) makes plurals of (most regular) nouns, and also makes 3rd person singular declension of (most regular) verbs.
