I think what makes it kink is the intensity of the emotion, for example most of us love eating, but some Really love eating to the point that they pick up a strawberry and you tell them to " get a room".

I like competency kink where someone does something very well and I'm on the floor slobbering.

I recently saw a ballet competition, and was getting some real balletkink / dancekink but that's almost impossible to pull off in a written work. If you see any, send it my way. ;)
