Someone who is only attracted to Disney Channel stars, Disney cartoon characters, and just Disney in general. Such people do not date REAL people who they actually have a chance with, but prefer to daydream about Disney Channel stars. They usually are fans of High School Musical, The Little Mermaid and The Lion King. Disnosexuals are usually preteens.
Lisa and I were at the mall when we passed a Disney store. Inside we saw all these preteen girls fighting over a Zac Efron pillow, a Jonas Brother's Diary, and a Hannah MontanaBarbie Doll.
Lisa: Jesus, what disnosexuals. They should get boyfriends.
A Disexual person (Sometimes known as Dyosexual) is someone who is attracted to exclusively 2 genders. These genders can be any 2 genders, if you're exclusively attracted to 2 genders you're allowed to use the label Disexual/Dyosexual.
It's very similar to Bisexual, but is not the same. Bisexual is attraction to 2 or more genders, while Disexual is attraction to only 2 genders. You can still use whatever label you like the best, though. You can also use them interchangeably.
I got most of this information from LGBTA Wiki, so credit to whoever made the "Disexual" page on there.
