    I believe that the reason most people use the terms interchangeably, is that
    usually you are using arp-spoofing as the technique to allow poisoning of a
    target's arp cache.  You can use arp-spoofing for other purposes, and you
    can poison arp cache using other techniques, but the two used together as
    described above is by far the most common discussed.
