The phrase combines two pieces of internet slang: bruh as a deadpan reaction to something foolish, and get recked as gaming slang for being decisively beaten. Neither part points to a single show, film or creator, which is why the clip circulates mainly as a short reaction sound rather than a quoted line. It spread through gaming highlights, fail compilations and short-form meme edits, where its sub-second length makes it easy to drop over a defeat. That simplicity keeps it useful whenever a creator needs a quick, sarcastic payoff.
