Basically, it's inspired on Caralho Voador by Faith No More which means something like flying fuck, an expression often used in situations where you don't really give a damn about it. So, cacavoladora or caca voladora it's spanish for flying poo (or flying shit, but less NSFW), which can be used in similar situations aswell.
Also, a slight variation of Caca Volante, a fan-site around Faith No More and Mike Patton's thousand bands.
And if you speak (at least a little bit of) spanish it's an easy to remember wording, so you'll probably remember the address, want it or not (?).
