The 'Bonjour Bear' meme features a high-definition photo of a polar bear poking its head out of a snowy den, typically paired with the simple French greeting 'Bonjour.' This reaction image first gained significant traction on platforms like Twitter and Reddit, where it became the go-to visual for signifying an unexpected arrival or a polite interruption in a digital conversation. Its popularity stems from the bear's curious and friendly expression, which contrasts humorously with the harsh Arctic environment. It is often used as the antithesis to the 'Adios' meme, representing someone re-entering a social circle or popping back into a chat after being away. The meme remains a staple of wholesome yet versatile internet humor, perfect for any situation that requires a soft and funny introduction.
