Que porra is a common Portuguese expression of surprise and frustration, roughly equivalent to an English what the hell, and short reaction clips using the phrase circulate widely in Brazilian meme culture and social video. Because the sound is only about a second long, it works as a quick, portable reaction that can be dropped into edits, streams and chat conversations without needing translation. Its popularity comes from that directness: one shouted phrase instantly signals disbelief, annoyance or comic shock.
