The act of being ejaculated in the anus, and then invaginating your anus with your arm to spray all of the liquids out of your anus. The prolapse is similar to the Pokémon, Blastoise's tail, and the liquid spray is similar to Blastoise's attacks, Water Gun and Hydro Cannon, but the similarity of either Blastoise attack depends on the intensity of the climax.

To forget proper etiquette when overcome with interest in or admiration for a new technology. Understood to be at best a faux pas, at worst a sin. Of Victorian origin.

When you're having sex with a girl and you're about to nut and you scream "HYDRO PUMP" before you give her a creampie.

Girl 1 - "Go get her then pussy, you won't"
Guy 1 - "Fuck you I'm gonna do it now!" *Leaves*
Girl 2 - "He's such a fuckboi lol"
