A couple version of a Pet the Dog moment. Basically, when a couple/potential couple -- who spend the entirety of the show yelling at each other, insulting one another, doing things to deliberately upset one another, stabbing each other in the back, etc. -- have a moment when they reveal that deep down, they really care for one another. Awwww. Often takes place in a humorous rushing-to-your-spouse's-defense manner, where one of them angrily defends the other against the same kind of insults that they themselves like to dish out. A similar phenomenon is often seen in brother-sister relationships.
