V. Getting with a friend on the swing and swinging your head back and putting your feet up, wrapping them around the chains and hanging. Usually includes laughing.

When you are deeply and truly in love with bathtubs. Whenever you see such a sexy appliance, you just can't help but feel compelled to be near it. They're just irresistible to bathtubsexuals.

"Hey, Marty? Do you see that bathtub over there? It's pretty hot. . ."
"Dude, are you a bathtubsexual?"
