1. When a couple is in their own little "bubble" while speaking to each other and anyone else outside of this "bubble" cannot get through
2. A couple-bubble can range from the two people in the bubble giving responses but unwillingly and half-heartedly because the person outside the bubble is attempting to "pop" the inclusive couple-bubble to being completely ignored
