A monster that hides under little Canadian girls' beds at night, especially girls named Katiie. They're deadly when provoked and will hit others in the face with guitars, or blast loud Eminem music until their ears bleed. Otherwise, they are quite cute and make awesome pets.
Little girl: MOMMY, MOMMY! There's a big scary monster hiding under my bed, but it's cute and I don't know whether to cuddle it or kill it. D:
Mom: Don't worry, it's probably just a Finlaymonster. Give it a cookie and everything will be fine.
