Bfs fam

My bfs fam is Vietnamese and he was telling me how his gf got an allergic reaction and her lips swelled up so he told me no offense but her lips looked like black people lips and was making fun of that . I'm Puerto Rican and I definitely have black ancestors I consider myself African , Hispanic and white but this just bothered me so much like his whole family was laughing about it I just found it racist and ignorant in a way there's nothing funny about big lips and o know plenty of Asians with big lips like why does he have to mention black people .
