I'll explain it to you.

So, the Chinese girl was looking through some photos (or a video) of her and her white boyfriend kissing in a bar, and she noticed a Chinese guy in the back (the guy with glasses) staring at them with disgust.

Then she posted it on social media, zoomed on his face and you can see in the translation that she's like "I'm so sorry for hurting this guy's feelings!… btw this is when my hair was pink hahaha!"
so, basically, she's making fun of the Chinese guy who was giving her and her boyfriend the death stare

How do you not understand it when the explaination to it is literally in the title? It's the title, plus visual evidence in the image.

I'm spoon-feeding you, but it looks like you have to switch back to lactation…
