Butt Out

"Butt out" is an informal English idiom, generally used as an imperative, meaning to stop interfering in something that is not one's concern. It is a direct and often impolite way to tell someone to mind their own business or to refrain from meddling in a situation where their involvement is unwanted or unwelcome. The phrase implies that the person being addressed is overstepping boundaries and needs to withdraw from the situation. The degree of offensiveness can vary depending on context and tone of voice.
