A wet dream that happens at an inopportune or embarassing time, typically during a public power-nap or quick mid-day snooze.
I fell asleep in class today for just a couple minutes and I had an embarassing snoozypie right in front of my professor!
Jeff got more than he bargained for when he tried to catch a nap on the subway. Everyone heard him moaning right before he snoozypied his pants. You should have seen his face when he woke up and realized what he had done!
