The Nefario Principle

The larger the mass of an object, the quicker the effects of the shrink ray wear off! I call it the Nefario Principle. I just came up with it now, actually.

dr. nefario 

Dr. Nefario is the most savage person in Despicable Me, but somehow, he NEVER became the main character. There must be some conspiracy around him, because of all of this terrible treatment. He made the INFAMOUS JELLY! IT TASTES LIKE F'ING HEAVEN! HE IS GOLD, HE GETS ALL THE WOMEN!!!!!!! But still, he is treated as an extra in all the movies. THAT'S WHY HE LEFT IN DESPICABLE ME 2!!!! HE COULDN'T TAKE GRU'S CRAP ANYMORE!

He is praised in his own religion, Nefarioism. WHEN YOU SEE HIM SOMEWHERE ANYWHERE, COMPLIMENT HIS GREATNESS!!!!!!

Can also be used as an adjective for somebody very very smart.

Dr. Nefario Is beautiful.
This kid is as smart as Dr.Nefario.

down nefarious

when someone is extremely distressingly horny

aiden: Holy fucking shit. I want to bang Jessica so goddamn bad. I can't stand it anymore. Every time I go to class I get a massive fucking erection. My dreams are nothing but constant primal animalistic sex with Jessica. I'm sick of waking up every morning with six nuts in my boxers and knowing that those sperm should've been fertilized inside of Jessica's tight ass pussy. I want her to have my babies.
max: you down nefarious
