This is what "yaoi" stands for,
parents! When your son/daughter mentions the word yaoi, this is what they mean.
YAOI is a nonprofit organization where underprivileged
children with a high IQ learn to ice skate. A very beautiful organization, but mainly directed at teens and
children.
If your son/daughter mentions YAOI and then begins to laugh, chances are they remembered a specific episode of YAOI which portrayed humor.
(For all non-parents here, you know what yaoi is. This is the definition you'll want to tell your parents - because it's right...)
Father: What are you reading?
Daughter: Uh, just some YAOI...
Father: What?
Daughter: Young Academics on Ice! It's,
eh, a really funny screenplay!
