Merda falante is a Portuguese phrase that literally means talking shit, and this clip is shared online as a short reaction sound for comedy edits and chats. Its appeal comes from its directness: in Brazilian and Portuguese internet humour, a single blunt phrase can stand in for a whole argument. Because the clip is only about a second long, it is easy to drop into memes, chats and short videos, which has kept it in circulation as a quick insult for boastful or nonsensical talk.
