Mlem is onomatopoeia from online pet culture, where captions describe a dog or cat's tongue flicking out as a mlem. The spelling took off in animal meme communities on Reddit and Twitter as captions for photos of pets caught mid-lick, and short clips of the sound itself began circulating on meme soundboards and in TikTok edits. Because the noise reads instantly as cute and hungry at once, creators keep reaching for it years later whenever a moment needs a small, wholesome burst of comedy.
