Toy Ship: A Toy Ship is a ship between two or more children (no teenagers or adults.) Toy ships are considered cute by some people, but are a squick to others. Children’s media fandoms probably have the most toy ships, since they tend to have more children as main characters. If the characters are aged up, it is not a toy ship.

We should bring this term back.

And maybe some terms for child x adult and teen x adult ships too… (I looked to see if there were any, but I couldn’t find them.)

It’d be great if there was an easy and memorable term for people to either search or to blacklist with regards to these types of pairings!
