Mermaid Head 

Immensely skilled, extremely enjoyable, high-quality oral sex. The type of head a mermaid would have to give in order to make up for the sexually-unusable lower half of her body.

Last night Ariel gave me Mermaid Head. It was so good, I almost didn't care that she wouldn't let me get into her pants.

Mermaid Vomit

Trend where it is fashionable to suspend pieces of shells, rocks, and sand in resin, often made into decorative pieces. The result looks like regurgitated mermaid vomit. The term "mermaid vomit" came into popularity on a thrift store Facebook page after disagreements on whether mermaid vomit was the same defined by "Vomit clock" Any object made this way can be called "mermaid vomit."

"Bea! Check out this Mermaid Vomit lamp ! Won't this go great in the bathroom??"

Cam: "what's that dude? Dave: "It's when you hang around her so much you start wanting to bone her even if you don't have physical attraction towards her"

Mermaid Filet 

The mermaid Filet is the process of opening the mermaid's tail. The girl ties her ankles together (making the mermaid tail) and the guy tries to enter her by any means necessary. The mermaid flips around on the floor like a fish out of water trying to avoid being speared.

Blackbeard was know for enjoying Mermaid filet on the deck of the pirate ship.
