Opposite Day Cards

Opposite Day is an informal, playful observance rooted in a children's game and linguistic joke in which participants say or do the opposite of what they mean. Its exact origins are unclear, having emerged organically in schools, playgrounds and popular culture during the 20th century; it spread through word-of-mouth, TV episodes, books and internet memes. The “holiday” has no official status or universally recognized date and is used primarily for humor, role reversal exercises, creative language play, and occasional classroom activities that promote perspective-taking and critical thinking.
