Any fanfiction where the authors personal fantasies get involved with the story, for example I was reading a story where this human called Max would get injured constantly and be put into countless near death experiences and would have his self insert get critically injured, but barely escape death to have the rest of the cast panic, cry and worry over him, now this wouldn't normally be bad if it happened once or twice, hiwever when this happens more then three times, it gets kinda cringy and predictable, sometimes it's enough to stop me from finishing a fic.
