mermaid hair

When a girl's hair is so long that when she is naked, her hair will cover her boobs entirely. Much like in some images of mermaids.

Betty: I have such mermaid hair right now!
Lisa: Dammit, mine's only shoulder-length.

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.

Gutter Mermaid

When you fuck a girl and drop a load in her, then she slips between the mattress and wall flopping around.

When I was done with Anna, I couldn’t find her but there she was stuck like a gutter mermaid.

Mermaided

When someone falls in love with you without you even knowing of their existence, like Prince Eric and Ariel from Disney's The Little Mermaid.

Dude, that girl from accounting just mermaided me. I don't even know her name and she is totally infatuated with me.

mermaid effect

When a guy has been hanging out with, or simply in the presence of a girl that is just a friend for long enough that she ends up becoming sexually desirable.

Based on the idea of sex-starved sailors who would see manatees frequently and eventually they began to see them as mermaids.

It was also used in the TV show How I Met Your Mother.

Guy 1: "So you're going to be rooming with a chick next year? watch out for the mermaid effect, if you hang out with her long enough, you know you'll end up wanting to hit that."

Guy 2: "Nah man, she isn't hot and totally isn't my type."

Guy 1: "I give it three months."
