mermaid tail 

When you fall asleep after sex and the jizz leaks out and glues your legs together.

Damn Meg, you should have cleaned up after that gang bang last night, now you’re mermaid tailing it.

Mermaid Tail 

A mermaid tail is a costume (usually made of swimsuit fabric, silicone or rubber) that can either be swimmable or just for show.
A mermaid tail allows you to look and feel like a mermaid by putting your feet into a fin covered by fabric to look just like the magical creature.

I can’t wait to get my Mermaid Tail for Christmas.
