shadowbathing
What you do when you've been in the sun for a while, you're hot and/or uncomfortable, and you need some shade. Shadowbathing is the opposite of sunbathing; it results in a nice cool feeling that is comparable to eating a freezepop with your entire body.
Yo Erica, we've been playing frisbee in this heat for four hours...let's break for lunch and do some shadowbathing.
