A relationship defined by being inherently undefineable. Nebulous in nature, this type of relationship teeters between the ambiguous and incomprehensible. A classic symptom of this kind of relationship is the response "I don't know" when the question "what's up with you two?" is presented.
We hang out a lot, but we aren't dating. We're more than friends, but...we're not into titles anyway. We have such a Ches relationship. I have a test, I gotta go.
