kaijou
Kaijou is a stupid abbreviation that fans use for Kaiba and Jounouchi. They hate each other like a broken toaster and a piece of burnt toast. Kaiba is the top dog in this messed-up relationship.
My friend ships Kaiba and Jounouchi and calls it 'Kaijou' which is just a fancy way of saying 'I'm a fangirl'.
I saw a tweet saying 'Kaijou is the worst but I still ship it.'
My mom called me Kaijou because she thinks I'm a fangirl who hates math.
