Errormare 

A ship between Error sans and Nightmare (he isn’t really a sans). Often confused with Killermare, but is way better because Killermare makes no sense. Don’t even get me started on Errorink. (I had to reupload this sorry lol)

Errormare fan: “My favorite Errormare fanfic was updated today!”
