Moothew Matthew Moo, also floating around as Zesty Cow and You Found Your Moo, is a TikTok audio edit that dubs a young calf's first moo with a clip of Zerobaseone member Seok Matthew mooing into a TikTok filter game1. The swap gives Daisy the calf a dramatically higher, sing-song moo that fans described as 'zesty,' internet slang typically used to mean flamboyant or effeminate4.

The joke works because Matthew's moo is theatrical and pitched way up, while the original farm clip is a quiet, uncertain first attempt from a real calf2. Once the sound started circulating, the audio itself became the meme, with users lip dubbing to the moo as if it were a diva line reading5.

The core format is the @inbloomie edit itself, so most participation is a lip dub or reaction rather than a new remix. Creators typically film themselves lip-syncing to the swapped moo, often in a diva or flirty pose, and lean on the mismatch between a farm setting and Matthew's theatrical vocal. Captions commonly play on 'zesty,' 'cvnty' or general Matthew-stan humor.
