DaBaby, the American rapper born Jonathan Kirk, made Let's Go one of his most recognisable ad-libs across his late 2010s and early 2020s hits. Short clips of the shout were cut from performances and tracks and shared widely on TikTok, YouTube and Discord as a reaction sound. The Swedish words in this version, varning högt, mean warning loud, signalling an intentionally boosted, earrape-style edit made for comic shock value. It remains popular because the phrase is instantly understood as hype, even by listeners who do not follow his music.
