The act of ejaculating on someones face while they are passed out drunk or in a deep sleep. They awake the next morning with dried and hardened semen all over their face and hair.
Last night my girlfriend came over and fell asleep early so I gave her a Sleepy Snowman. She was pissed when she woke up the next morning.
