Meaning
A full-body cow standing in profile, usually white with black patches, sometimes with a small bell or udder visible. It means the dairy animal itself, as opposed to the cartoon face 🐮.
It fits farm life, cheese and milk posts, countryside trips and the exclamation holy cow, often with 🥛 or 🌾. Example: “Holy cow, we drove past a whole field of them on the way to the lake 🐄”.
