Idk. But I remember my mom calling a 肥仔 in a light-hearted tone and I sort of felt the endearment… like my first instinct was oh mom’s teasing me again, like I didn’t feel offended at all, just annoyed that it become my nickname. If I had to make a comparison: I guess it’s sort of like calling a fat cat a “Chonker”

I wasn’t even that fat by American standards lol, literally at the time, in school there were kids bigger than me in the same grade.
