5. Lurkulator
Coined by Mikey Rocks of the Cool Kids. Synonym for creeper.
"Whenever you see anyone lurkin' real hard, you gotta call 'em out. Make 'em aware you see 'em. You gotta sing the lurkulator song. 'I'ts time for the lurkulator. It's time for the lurkulator'. It makes them uncomfortable and want to remove themselves from the situation."
