The phrase "how hungry horse" most commonly refers to a humorous meme derived from the saying "I'm so hungry I could eat a horse." The meme features a comic or tweet where one character says they are very hungry, and then a horse nervously asks "how hungry?" This playful interaction has become a popular internet meme format used in various social media posts and comics.
If the question was about the literal hunger of a horse or the phrase's meaning, the meme itself is a humorous take on an idiom expressing extreme hunger, not a literal inquiry about a horse's hunger. If the interest is in the literal care or feeding of a hungry horse, additional information would be needed, but based on the common usage, "how hungry horse" refers to this meme and internet joke. If more details are wanted on the meme origin or meaning, that can be explored further. Otherwise, this is the primary relevance to the query.
