What is be there or be square?

"Be there or be square" is a popular idiom, particularly among younger generations. It's essentially an invitation or a warning, implying that an event will be exciting or important, and those who don't attend will be considered uncool or "square" (meaning boring, outdated, or not with it).

The phrase emphasizes the social pressure to attend events and the fear of missing out, or <a href="https://www.wikiwhat.page/kavramlar/FOMO">FOMO</a>. It's often used lightheartedly but can carry a subtle implication of social exclusion. The opposite of being "square" in this context is being "hip", "cool", or "in the know". The phrase plays on the desire to be part of a perceived desirable group or experience. The etymology of using "square" to mean uncool likely stems from the shape's association with rigidity and conformity, contrasting with the more fluid and dynamic image associated with coolness. While its exact origin is debated, its widespread use began in the mid-20th century and continues today.
