A phrase used to describe having sex when around young children.
(wives sent their husband to take the kids out for ice cream)
Husband A: Yeah, last night was awesome. Because me and Becka did the happy for two hours.

Husband B: Woah man, that's a record.

Kid A: What does that mean, daddy?

Husband A: Oh, it means to have fun! Now go run along!
