The exact origin of this recording is unclear, but the phrase loei doet de koe belongs to a familiar Dutch way of describing farm animals in children's speech and nursery rhymes, where each animal gets its own verb for the sound it makes. Clips like this circulate on soundboards because the line is instantly recognisable to Dutch speakers and sounds funny even to those who do not understand it. It has found a second life in memes and short videos, where creators use the cheerful delivery to underline anything cow-related, from farm footage to dairy jokes.
