Well, this is yuri. When you get to the bottom of it, yuri stands for girls' love. What we have here is Pan-chan clearly thirsting hard after An-chan (we don't yet have a clear idea what Meshi's status is.) As for the other term thrown around, it is alien to the origins, and thus devoid of any meaning. The less it is used the better.
Now if you want to see a real bloody fistfight in progress over terminology, check any discussion over the matter of degrees of subtext-only stuff, and whether they should be called yuri...
