ELI5: Explain Like I'm 5

Category O

Okay, picture going to a store with your mommy or daddy. Imagine different sections of the store, like a toy section, a candy section, and a clothing section.

Now, sometimes there are things in a store that are too intense or not appropriate for children to see or play with. These things might be put in a different section called "category O". The "O" stands for "obscene".

So, if you're a kid, you might not be allowed in the category O section of the store because it has things that are only for grown-ups, like magazines with pictures that aren't appropriate for children to see.

Basically, category O is a section of the store (or internet) with things that are only for adults because they are too intense or not suitable for children.
