Exactly, it's a joke.

I had a friend who has both eyes like that I think. So he needed glasses. Don't talk to that guy anymore...

It's not really a word, it's a street word really you can just say anythingslop

My friend (secretly):

Is it like, one eye's muscles are too tight or something?
(I also might have dyslexia, so that certainly doesn't help my case)
