The 'Bear Walks by a Bus' meme originated from viral footage showing a massive brown bear casually strolling past a bus filled with tourists, highlighting the sheer scale and power of the animal. It quickly became a popular internet template used to represent an overwhelming force or a massive problem that is 'just passing through' while the subject tries to remain calm. The humor lies in the bear's nonchalance compared to the potential chaos it could cause. It is widely used to joke about impending responsibilities, social anxiety, or any situation where a giant, unavoidable reality looms close by.
