When you have no other choice but to take a nap in extremely high temperatures. These naps do not last more than two hours and have been proven to put the person in a very awful mood.
Last summer on a road trip, Ryan and I were forced to take a hot nap in the car in Nevada before continuing on to California.
Really a hybrid of the dutch oven and the hot carl. First you eat nothing but crepes, eggs, and cheese for a week, then wait for your lover to fall asleep and get a good French fart built up. Put your asshole over their nostrils and let rip.
