Pogue Mahone comes from the Irish phrase póg mo thóin, literally meaning kiss my arse, and it entered wider English use as a cheeky, old-fashioned way to tell someone to go away. The words also became widely known through the Irish band originally formed under that name, later shortened to The Pogues, which helped carry the phrase beyond Ireland. Online, the short spoken form survives because it sounds distinctive, slightly rude and instantly dismissive without needing explanation, making it a handy shorthand for creators who want a quick, memorable put-down.
