When @AtlasSmugged sees a pretty woman, he wants to cry and throw up. Presumably, this vomiting and tearfulness arises out of jealousy for our ciswomanly bodies. Thing is, I’m a woman and I know women. When women see other women who’s bodies we’re jealous of, it doesn’t make us want to cry and throw up. That seems pretty extreme.
@AtlasSmugged’s friend, @tulsy, wants to be the object of that jealousy. She doesn’t think it’s weird at all that looking at pretty girls makes her pal want to cry and throw up. She just hopes he’s crying and throwing up over her.

First thing that came to my mind was jealousy of female bodies (of which he will never have). You are right crying and throwing up would be an extreme reaction and one only a female would be likely to be have because women’s live are so stressful compared to men (who have everything handed to them).
