The phrase itself is a stylised version of top of the morning, a greeting long associated with stereotyped Irish speech in film and television. This clipped version, written as top o' da monin', spread on soundboards as a Kendrick labelled meme audio, shared in short form edits and reaction posts rather than as a full song excerpt. Its short chant like delivery made it easy to loop, caption and reuse, so it stuck as a go to morning greeting sound even outside any music context.
