Reverse Mermaid 

Someone with the upper body of a fish, and the lower half of a broad.

The reverse mermaid is much more key to throw it in than a regular mermaid. The only thing you can do with a normal mermaid is oral or get rubbed out, with a reverse mermaid you can go anal, in the vag, or even in the sloppy fish mouth.

Reverse Mermaid 

The sexual act of copulating from behind while dunking their head in the bath.

My hair is wet because my boyfriend just did the reverse mermaid on me.

Reverse Little Mermaid 

When you give oral stimulus so vigorously that you end up being unable to speak for three days, like Ariel from The Little Mermaid. Just with more oral sex.

1: Hey, why's your girl not speaking?
2: We got a little intimate and she gave the reverse little mermaid, if you catch my drift
