Misspelt version of "promiscuous".

permiscuous 

A word that people thinks means sleeping around a lot but is actually spelled promiscuous, dumbasses.

I don't think anything could be permiscuous because that isn't a word.

Pernicious Love 

Having love for somebody that causes harm towards you, knowing full well it’s bad for you. You want to stop, but you always come back.

“I don’t understand how she keeps coming back to that monster!”

“She’s feeling pernicious love.”

pernicious

Describes something that really messes you up. Most of the time you can't tell at the beginning but before you know it, it really fucks you up.

Person 1: It ain't worth it bro, you know Prozac is pernicious. Don't take it.

Person 2: Too late, I can't get off of it now.

Person 1: Damn, I hope you don't get erectile dysfunction like that other kid.

Person 2: Too late for that too...
