toxic seahorse 

Based on a Mega Man X character, a 'toxic seahorse' is anything that makes as little sense as possible.

My friend John Paul makes about as much sense as a toxic seahorse.

Seahorse 

When a man's semen ends up on his stomach, either by his own handywork or with the help of another; inspired by the species' method of reproductive development wherein the male carries the embryos on his stomach region.

I didn't have any tissues near by so i just seahorsed myself and passed out.

She doesn't like to swallow, so she usually just gives me the ol' seahorse.

As you're fucking your special someone...the man begins to do the "white boy can't dance" move while inserting his penis into her vagina.

PJ was doing the mechanical seahorse while screwing Luke up the ass.
