Fudanshi 

A boy who enjoys yaoi. This word is commonly misunderstood for a boy who enjoys Yuri (a boy who enjoys Yuri would be called a himedanshi, which literally means princess-boy). Literal translation of Fudanshi is “rotten boy”. Although it has originated from negative sources, the word has been reclaimed.

Person 1: Wow, he reads yaoi? Is he gay?
Person 2: No, he’s straight. He’s probably just a fudanshi.
