I commented "serving irl moon emoji 🌝" on one of my str8 friends IG posts. How do i explain this?

Looking dope

Just tell him you're gay and you didn't mean what you said

serving = what the person looks like/what they are representing/or what they are similar to

She is serving ariana realness = she looks like ariana
she is serving demi vocals = her singing is as good as demi's and they sound similar
she is serving cavewoman at a garage sale = she looks dirty and cheap

Tell him to watch Paris Is Burning

I dont even kno what you are trying to say with that tbh.

I wasn't saying that he looks dope, I was referring to his fat round moon-looking emoji face.

"Your face is fat."

You could always say "You're giving me..." instead.
