Evapulation 

When you cum on your belly and then fall asleep only to find the cum has disappeared when you wake up.

I experienced some severe evapulation when I woke up this morning. Where does it even go?

Vindaloo evacuation 

When you have a roaring hot diarrhea of fire the day after having consumed very spicy foods, such as a Vindaloo curry. This usually happens first thing in the morning, mere minutes after you wake up, and it stings even worse going out than it did coming in.

Man, last nights curry was friggin' delicious, but it resulted in a painful Vindaloo evacuation early this morning.
