AIO for Shutting Down My Friend’s “Joke” About My Weight at a Party?

Last night, a group of us were at a rooftop bar celebrating a friend’s engagement. I (28F) wore a fitted dress I’d been excited to debut—first time feeling fully confident in my skin post-pandemic weight gain. Everything was great until Mark (30M), a friend of the groom, loudly said, “Damn, someone’s been enjoying lockdown takeaways!” while looking directly at me. The table went silent.

Without missing a beat, I replied, “And someone’s still failing at basic human decency. Congrats on consistency.” Grabbed my coat and left. The bride (my best friend) texted that I “embarrassed Mark” and should’ve just laughed it off because “he’s socially awkward.”

Now half the group thinks I was too harsh, while others are DM’ing me screenshots of Mark’s past shady comments about women’s bodies. AITA for refusing to be the punchline?
