Mine is "guinea pig" originating in andes (not guinea) and them being not-a-pig type, whole thing is just wrong.
We really ought to pick one of these names to start calling them:

I'd be partial to the Muscogee word because I'm from the Southeast (and because it starts with 't'), but it doesn't seem like it has enough vowels so I have no idea how to pronounce it.
