The phrase is Polish, with dawaj working as a casual call to get going, and the clip has circulated online as a short hype shout rather than as a line from a well-known film or show. Its appeal comes from that everyday, spoken feel: it sounds like something shouted between friends, not performed for a camera. In meme and gaming edits it is usually dropped at the turning point of a clip, where a quick burst of encouragement makes a hesitant moment feel decisive, and its brevity keeps it easy to reuse without slowing a fast edit.
