The phrase "where it ats" is commonly used in English to ask for the location of something or someone. The correct spelling is "where it's at", with the contraction of "it is". The pronunciation of the phrase is /wɛr ɪts æts/, with the stressed syllable on "at" and pronounced with a schwa sound. The use of "ats" instead of "at" is a common misspelling or slang variation, but it is not considered grammatically correct or standard English.
