The line comes from the Showtime series Dexter, which premiered in 2006, where Sergeant James Doakes, played by Erik King, uses it as his signature greeting when confronting Dexter Morgan. Clips of the moment circulated on YouTube and forums in the late 2000s and grew into a long running Dexter meme, reused as a reaction to reveals and ambushes. Its short length, instantly recognisable delivery and perfect timing for cutaways kept it in meme edits, gaming videos and soundboards long after the original series ended.
