Blastoiseing 

When you hold your nut in several days till max capacity and then during sex as you gush semen out of your canon, yell “hydro pump!” To then curl up in your shell and go do sleep after a battle well done.

After a long month of No Nut November, Tyler went Blastoiseing. Best sleep he ever had. Turns out his wife is pregnant though. They are expecting a lil squirtle in 9 months.

Blastoise 

A personality of someone during the act of sexual intercorse that likes to ejaculate all over the place during sex. A blastoise is also a water pokemon so water and semen are closley related. Therefore when Blastoise uses water cannon, the males dick uses semen cannon.

Me- Are you a blastoise Johnny?
Johnny- No i don't even have a dick you cunt.
Cortney- I am.

Blastoise 

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.

To blastoise is to blaspheme, gentlemen, against good Mother Nature, and against your humanity.
