Waltuh comes from Breaking Bad, where Mike Ehrmantraut pronounces Walter White's name that way, and the stretched pronunciation became a meme format online in the early 2020s. Clips isolating the name were remixed, pitched up and reposted across TikTok and YouTube as a chipmunk laugh style edit, similar to other pitched voice memes. The chipmunk version keeps only the recognisable name and delivery, which makes it easy to drop into unrelated videos as a quick reference that fans immediately understand.
