The line comes from The Next Episode, Dr. Dre's 2000 single featuring Snoop Dogg, Kurupt and Nate Dogg, taken from the album 2001. Snoop delivers it as the last ad-lib as the track fades out. In the early 2010s editors lifted that ending for montage parodies, MLG edits and weed-themed remixes on YouTube, where the deadpan sign-off became shorthand for stoner humour. It later spread to Vine and TikTok, and still works because almost everyone recognises Snoop's voice instantly.
