You've met this person who is a toxic fruitcake shipper..!! They force their ship onto other ship and said that fruitcake is "canon".... Which it isn't..

They hate Cosmo or Sprout ship and only like fruitcake since it's "canon".. They sent death threat to people who like other ship than fruitcake such as moonberry or fossilcake.

Toxic Fruitcake Shipper: "WHY ARE YOU SHIPPING MOONBERRY?! FRUITCAKE IS CANON!!! I SWEAR I WILL COME TO YOUR HOUSE AND K1LL YOU, YOU STUPID FREAK...!!!!"
