today me and one of my friends who is on the bigger side were talking about making cakes for mothers day. Eventually she told me how many cakes she, me, and her other friend were making and I said “thats a lot of cake” because it seemed like a lot for just us 3 and she quipped “ive heard that before” right after. without any thought behind it or even remembering her weight or that it may be offensive I said “from the waitress” just to play off of what she had said. i did not mean it or intend to make her feel bad at all as i was just trying to keep the joke going and i would have said the same joke to anyone including thinner people. jokes like this are very normal in my male friend group and we never mean them in the slightest so it just rolled off my tongue. My autism also makes it harder to understand if something is appropriate or hurtful. that doesnt excuse my actions in any way i just feel like there needs to be some clarification on why i said it. i regret it so bad and feel horrible idk what i can do to make it better. i wish i wasnt so socially inept.
TL;DR i made a fat joke without thinking about who it was towards
