The line comes from the first episode of Narcos, the Netflix crime drama that premiered in 2015 and follows the rise of the Medellín cartel in Colombia. Spoken in Spanish, vamos a darles plomo literally means let's give them lead, a blunt way of saying to shoot at someone. Clips from the series circulated widely as short audio memes, and this phrase stuck because it is short, instantly threatening, and easy to place before action. It remains popular in Spanish-language edits and gaming videos for signalling that a confrontation is about to begin.
