I'm with you - screaming in orgasms throws me straight out of porn. I'm okay with "cried out" (although, even that I narrow my eyes at if it's m/m sex, since it implies a higher pitch, to me), but even words like "shouted" or "yelled" bug me, since I associate those as verbal noises. As in, a nonverbal shout is a super weird concept to my brain, so it seems out of place without accompanying dialogue in the scene.

I honestly almost always assume it's just lazy writing/lack of creativity. I tend to not come across it much anymore since the rest of the fic tends to be give away the game before I hit orgasm time, and I've back-tabbed out already. :D
