What's the worst fetishisation you've ever seen/read?

I'll go first.
I once read a book where the MC was a stereotypical twink, and the ML was the 'STRONGEST MAN EVER'. But everyone was saying that the mc was actually the top/gong, and I was interested because ppl don't usually make the small skinny one the top/gong.
Only for the author to ( midway through the book, just as the romance started kicking in ) describe the mc gaining 20 pounds of muscle, a six pack, 7 inches of height, and a fat cock all within a 2 month period. And the Male Lead suddenly loosing all fighting capabilities, loosing his 6-pack, growing hair to his waist, not having any pubic hair, having an uncircumcised cock and suddenly aspiring to be the MC's stay at home wifey.
I'm SICK to this DAY.
