make some mermaids

To "make mermaids" is to shoot jizz into a toilet. After flushing, the sperm reach the ocean, inseminating fish of the female variety. The fertilized egg will develop into a mermaid or merman, depending on the whether the sperm carries an X or a Y chromosome.

Because merfolk are a sterile hybrid (that is, they cannot reproduce), the continued existence of merfolk culture is contingent on the ongoing flushing of semen. Please give generously.

Person 1: What are you gonna do when you get home?

Person 2: I'm gonna hit the shower, make some mermaids, and do some homework.

Person 1: You know, shower jizz doesn't technically fit the definition given above.

Person 2: Well at least it's clean of shit.

When you jerk off and bust your load into the toilet and flush it.

They call me Poseidon because I'd be making mermaids, I'm king of Atlantis!
