When your family only consists of two consenting adults, preferably married or in a long term relationship, and it's time to bone down. Often useful as a suggestion when in front of others, but without saying "let's go have sex now."
Before we go have dinner with those people, we need some family fun time.

Oh, I'm sorry, we won't be able to make it to church this Sunday. We have family fun time scheduled all morning.
