Little did this cat know, but his so-called “best friend” was giving him bunny ears.

Wikipedia says:

Bunny ears – used with palm near someone’s head, from behind, indicates friendship or partner, as folklore of the American Cowboy as did the Lone Ranger and Tonto, who wore two feathers in a V. Typically for a friendly photograph. Sometimes this gesture is performed discreetly to mock the other person in the photo, with either friendly or unfriendly intentions.

It’s fairly obvious that this was meant to humiliate its victim.
