Irish Spring is a long running soap brand known for its bright green bars and fresh scent, and the color phrase became an easy shorthand online for anything intensely green or just cleaned. As short chant clips spread on soundboards and in meme edits, Irish Spring Green was clipped, shared and reused out of context, detached from any advert. Its popularity comes from that instant recognition, with viewers understanding the clean and green joke even without seeing a product, which keeps it useful for reveals, parodies and reaction edits.
