Meemo

An especially horny mermaid or merman. One that is showing excessive thirst, especially to humans.

Person 1: Gotta watch out when swimming today.
Person 2: Why? Sharks in the water?
Person 1: No, worse. I heard there is a meemo. Will drag you down and have its way with you.

Prince Eric knew what was up. Ariel was sending out big meemo vibes.
