We recently saw the movie RV (which I highly recommend - hilarious!) In one scene, the father is showing the family the slide-out. He pushes a button and one section of the room slides out to make the interior of the RV larger. He says, "Isn't that cool?" And his teenage daughter says, very sarcastically, "Macarena cool."
On our fouth cruise night, the waiters in the dining room all gathered around to lead everyone (or at least everyone who wanted to participate) in dancing the Macarena. How cool is that? Yeah. Macarena cool.
