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.

When you are banging your girl in the shower, and right before she orgasms, you hit her in the head with a can of tuna. Preferably the four-pack. “You wanted to know what a #ScreamingMermaid was right??!!
My girl begged me to tell her what “The Screaming Mermaid” was, so I banged her in the shower, and before she came, I hit her in the head with a can of tuna. She was so bewildered, she didn’t even ask me why Tuna was in the shower in the first place.

A given time before you realize that you wanna bone a female that you don't have any sexual or romantic feelings towards, even the most unattractive chick you see daily can in-fact have a "Mermaid Clock"
Dave: "yo look at jessica ?" Cam: " yeah she's ugly asf" Dave: "dude wait until she hits her mermaid clock"
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"

Man I was such an emo mermaid last night. I was sitting on the floor for six minutes trying to get my red skinny jeans over my feet.

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.

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.
