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.
