When a fan of a series (usually a woman) is too afraid to do anything that might offend another fan's fictional husband.
Emma: Oh my gosh. Nico is so hot.
Kate: You know he's gay, right?
Emma: WHAT DID YOU JUST SAY TO ME? NICO LOVES ME MORE THAN ANYONE! YOU'RE JUST STUPID, SHUT UP!
And that's how Kate's husband issues began.
