When you wrap your partner's legs in a sheet or blanket then either defecate, urinate, or ejaculate on their face at which point they creep around like a mermaid out of water looking for something to wash their face.
Hey Kim are you going out with your boyfriend tonight.

No, he gave me a creepy mermaid last night so we are seeing other people now.
