The phrase “it ain’t me” is a colloquial expression that means “it’s not me.” It’s often used to deny responsibility or involvement in a situation. The phrase gained popularity through its use in songs, such as “It Ain’t Me” by Kygo and Selena Gomez, where it conveys themes of distancing oneself from someone else’s problems or emotional struggles. In a broader sense, it can reflect a desire to assert one’s independence or to clarify that one is not the source of a particular issue or feeling.
