The phrase is Russian internet slang, with a softer form, 'a mne pokhren', also circulating in memes and chats as a milder way to say the same thing. Online it is shared as a short reaction clip and voice message, which is why it is now recognised mainly as a shareable reaction sound. Like the Bruh meme, it works because the attitude is instantly readable even without translation, and Russian-speaking creators continue to reuse it to puncture drama, hype, and complaints in short videos.
