Eita is a common Brazilian interjection for surprise, similar to wow or whoa, and colega means colleague or buddy, so the phrase is widely understood across Portuguese-speaking social media. Short voice reactions like this spread through WhatsApp audios, meme pages and short video edits because they are easy to reuse out of context. The clip stays popular as a light, non-serious response to gossip, surprises and embarrassing moments, where a full explanation would kill the joke and a familiar spoken phrase does the work instantly.
