The phrase comes from Spanish-language edits of The Lorax, the 2012 animated film based on the Dr. Seuss book, where work and hustle jokes were dubbed and remixed for social media. In Spanish slang chambear means to work a job, so repeating a chambear turns the line into a playful work anthem. The clip spread through TikTok, WhatsApp and meme pages in Latin American communities, then wider as a reaction to starting shifts, studying or doing chores, and it remains popular because the chant is simple, rhythmic and instantly understood.
