The act of sticking a metal rod into your asshole and going outside during a thunderstorm. In this act, a person would let a lightning bolt hit the metal rod in their rectum, hereby electrocuting their anus in a painful, yet satisfying way.
“Yo im thinking of hitting a devious dirty pikachu out in the storm tonight, wanna help me get the metal rod up there?”
“Yeah of course!”
“Yeah of course!”

Let’s be honest here, eevee is much better in everything wise, but it would help if pikachu wasn’t the mascot for every fucking Pokémon game. Have you ever seen a Pokémon game that doesn’t have a pikachu in its title nowadays? Well I have too but still

Get the Pikachumug. Stupid fucking pancake who won’t stop back-airing and dodging all of your moves like the rat it is. Pikachus are usually unnecessarily powerful and are known to cause massive amounts of tilt.
