"Fat shemale movies" seems to refer to films that feature characters who are female-to-male (FTM) transgender individuals or explore themes related to gender identity, specifically focusing on characters who are feminine-presenting or assigned female at birth but identify as male or masculine. These films might not necessarily be about individuals who are overweight or "fat," but rather they could explore a range of themes including gender identity, transition, and experiences of gender non-conforming or transgender men.
