What is Ouransyndrome?
1.
when someone in a manga (japanese-type comic, for example ouran high school host club) has difficulty realising that they're in love with someone, and it takes them at least 10 chapters, (one or two volumes) to work it out (when they think it's some kind of illness/heart attack etc), and then another so much to come to terms with it/ resolve it.
manga/anime freaks may use the term between them.

"haruhi soooo has ouransyndrome for tamaki"
"oh, stop with the ouransyndrome, and admit it already... there's nothing wrong with a bit of yaoi."
