How it's used

This term is a derogatory way to describe someone or something as foolish, immature, or nonsensical. While it originates from the English letter B, it functions as a mild insult that is often used among friends to tease each other for silly behavior. It is informal and should be avoided in professional or formal settings.

Examples

Why are you acting so stupid?
The things he says are really childish.

Common phrases

very stupid/childish
a stupid person

Common mistake

Do not use this to describe someone with actual intellectual disabilities, as it is highly offensive and insensitive in that context. It is strictly for describing behavior or ideas that are perceived as silly or childish.
