Poxy means wretched and worthless, in coarse use. A poxy little job, poxy weather, this poxy thing.
It is mild British slang and it dismisses rather than describes — a poxy amount is simply too small to bother with. It comes from pox, the old word for smallpox and syphilis, which is why it once carried real venom and now carries almost none.
