This usually involves a bigger area of water such as a pool, hot tub, etc. This is when a woman gives oral under water until the point of climax without coming up for a breath . when giving the oral it's important the woman doesn't swallow the cum but let's it float in the water and puts it in her hair like a mysterious mermaid would wear pearls.
I went to the hotel and this random bitch gave me the mermaid. I gave her a lot of pearls for her hair

Get the mermaiding mug.
A fandom in which a woman (or more rarely a man) either buys or makes a mermaid tail for the purpose of swimming in pools, lakes, or just posing on the rocks, usually while being photographed. Occasionally done with other mermaids.
Hannah got her new tail in last week and can't wait to go mermaiding in it.

A half-fish, half-human female who is very sexy and has a beautiful voice. Reminiscent of ancient Greek legends of Sirens or sea women who, with their sweet voices, would lure sailors to their deaths on rocky shores.
I met a hot mermaid chick who gave me the best blowjob I ever had.

Girls who cannot relate to boys on any intellectual level. They are only able to use their looks or sexuality to get attention. Jealous of girls who are able to use both.
The Mermaids saw the Wendies laughing with the boys and decide to drown them.
