What's your favourite weight gain trope?

[kevintheawesomeness]

For me it's extreme bulking, where a shredded girl has to grow muscle mass for some reason, gets carried away with food while aggressively weight train and ends up much stronger and fatter with a lot of flabs on top of the muscles. She then loses control and keeps on eating massive amounts of food so the fat continues to pile on. Finally she gives up on the diet but decides she needs to bulk up even more muscles to carry the fat... then the cycle continues... 

 

I think Fattening the Personal Trainer by @>_< 0_0 is the closest thing to this trope, but I really wish there were more out there 😕
