Slenderbone 

a fictional story about how the critically acclaimed slender man goes around raping college girls. My girlfriend just said that he was totally not raping them, just taking their virginity. Now she is trying to defend slenderbone. Totally weird and with some smutty lesbian sex scenes in it too.

Yea, it was weird..

"Did you read Slenderbone yet?"
"Totally, not worth it"

Slenderboi

When you're looking for Slenderman, but you're about to shit your pants in fear, so you try to lighten the mood by calling him this name (which he finds quite insulting) and saying it in a high pitched and funny voice. When attempting to find Slenderman, it is yet to be proven if this will increase your chances of success in finding him, but it will make your twitch viewers piss themselves with laughter if you say it with enough pathetic fear in your tone.

Slenderboiiiiiii! I know you're around here somewhereeee! i'll promise not to cry too much when I find you if you come out and show yourself! SLENDERBOIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII!!!

Slenderport 

When someone appears behind you and you don't know where they came from, like they teleported behind you. This commonly happens in the game slender.

Slenderman + Teleport = Slenderport

They just walked up behind you casually, but you don't know they're there. So when you turn around, they scare the sh*t out of you.

I was peeing in a bathroom, I thought i was alone. But when I was finished and turned around, THERE WAS A GUY STARING AT ME!!!!!!!

He slenderported behind my back.
