naisho
A person so creepy they make your skin crawl like a spider that just ate your dog. People think it's a typo but it's not. It's like Naish but with an 'o' and a side of disrespect.
"You’ve been following me since third grade. That’s not creepy. That’s a Naisho."
DM: "Why are you wearing my ex’s shirt? Are you a Naisho?"
Teacher: "Why did you hide in the closet? Are you trying to be a Naisho?"
