The phrase is Brazilian Portuguese slang, with Ué expressing surprise and Que p é essa? asking roughly what on earth is that, using a shortened swear word. Short reaction audios like this travel widely on Brazilian social media, messaging apps and gaming clips because they are instantly understood even without context. The sniper reference in the title suggests it is used after a long-range shot or an unexpected hit, though the exact original recording is not documented. Its appeal is its tone: blunt, funny and relatable whenever something looks completely wrong.
