Muralhoso V3 circulates online as a standalone soundboard clip with no clear single source attached to its listing, so its identity comes from how creators reuse it rather than from a confirmed scene or performer. The V3 in the name suggests a revised version shared among users who collect short reaction sounds. It has stayed in use because the length suits edits, memes and chat replies where a one second sting feels too abrupt, giving editors a recognisable audio cue that audiences learn to associate with a joke.
