When you stick your face in between your partner's butt cheeks, put your lips together, and blow like your making your own hot tub in the bathtub. Also known in some circles as speed boating, or motor boating the backside.
The wife thinks it tickles when I go Hot Tubbing, but I think it's fun. So long as she doesn't fart on me!

Finding a tubby kid and rubbing his tubbiness in a circular fashion until via friction he becomes hot. Hot tubbing.

She lies down and opens her legs, they come and take a ticket and they start hot tubbing her one by one.
