So in light of recent chapters blurring the definition of jinchūriki even more than it already had been, I figured I'd make this topic to discuss it. What exactly is and is not considered a jinchūriki, and why?

Things that do make you a jinchūriki:
 * Having a tailed beast sealed inside you with fūinjutsu.
 * Having Kurama's Yin or Yang half sealed inside you with fūinjutsu (Naruto and Minato).
 * Ripping a piece of a tailed beast's chakra out of Ten-Tails' jinchūriki, no fūinjutsu required (Obito).
 * Being given a small amount of chakra by a tailed beast, which it can then project its consciousness to (Naruto).

Things that explicitly do NOT make you a jinchūriki:
 * Eating the flesh of a tailed beast and gaining a (seemingly regenerating) supply of its chakra (Kinkaku and Ginkaku, unnamed Kumo resident).

Things that may or may not make you a jinchūriki:
 * Absorbing a tailed beast's chakra from its jinchūriki (Kisame and Nagato).
 * Being given the combined chakra of a jinchūriki and their tailed beast (the entire Allied Forces).
 * Keeping a piece of a tailed beast's chakra after its extraction (Killer B).
 * Absorbing tailed beast chakra into Susanoo (Sasuke).

Anything I'm missing? And can anyone even begin to make sense of all this?

Based on the fourth criteria, Kakashi should be a (former?) jinchūriki of Kurama, since he was given chakra directly from the beast itself just like Naruto, yet nothing in the manga ever implied he actually is/was considered one. Would Kakashi only be considered a jinchūriki if Kurama chose to appear in his mind, like the others did with Naruto? If so, does that mean Obito wasn't actually a jinchūriki of Shukaku and Gyūki, since they never appeared in his mental space?
