The origin of the 'I love you mere kale' clip is undocumented, with no confirmed recording, artist or source work attached to it in the materials provided. It appears to circulate as a user-uploaded soundboard snippet, the kind of short voice line that spreads through memes, edits and personal dedications rather than through an official release. Its staying power comes from the phrase itself: short, affectionate and just strange enough to quote. Without a verifiable source, it is best understood as an internet soundboard curio kept alive by reuse.
