The line comes from Don't Hug Me I'm Scared, the British surreal puppet web series created by Becky Sloan and Joseph Pelling, first released in 2011. It is spoken during the creativity lesson of the debut episode, where a talking sketchbook instructs the puppet housemates and dismisses the colour green as uncreative. Clips of the show's songs circulated widely on YouTube for years, and the blunt one-liner later broke out as a standalone meme on TikTok and soundboard sites, where creators repurposed it as a dry verdict on anything plain, safe or visually lazy.
