It should be called undefined vacation, because there's clearly a limit, unless taking half of the year off is fine.

That definitely hasn't been the case for me. I've had unlimited vacation and take off 4 weeks a year + assorted random days off (2/month).
I would never work somewhere with constrained vacation. Having to file paperwork for a random day showing family around town is ridiculous.
That being said, I think "untracked" is the best definition. It's obviously not unlimited, but there's also no hard limit. And the limit depends on behavior (leaving for 6 weeks is frowned upon, but 3 random days off every month is fine).
I've taken as many as 44 days off, which is a lot more.
