fatmaxxing 

A term used on 4chan's /lgbt/ board to refer to the technique of deliberately gaining weight in order to soften one's bone structure or accentuate features such as hips in the hopes that it will improve passing chances, a process typically (but not exclusively) undertaken by transfeminine individuals.

I thought my shoulder-to-hip ratio was going to be the death of me as far as passing goes but after fatmaxxing my hips have filled out enough to where it isn't an issue anymore.
