a yaoi jam is like a traffic jam, only with yaoi pairings in a fangirls head.

Its when you have more than one of your favourite gay pairings with hot anime guys in your head. And that causes that you can't concentrate on just one imagine of two bishies making out, not to mention you can't concentrate on math exercises or anything like that. So a yaoi jam makes you sit around in school blushing and grinning with your yaoi rapeface and drooling or nosebleeding while your teacher talks about worldwar 2. That can be problematic. The solution: DON'T read/watch so much yaoi mangas, fanarts and fanfics.
yaoi jam can also be used as a secret code to tell your friend you are in trouble:
fangirl 1: hey hey I have YJ
fangril 2: oh fuck. I feel your pain....by the way... which pairings?
fangirl1: Jin/Ragna, Jason/Nigel, Ciel/Sebastian
fangirl2: *drool nosebleed rapeface*
fangirl1: -___-''
