Big brain means: Very intelligent; genius.. It is internet-era slang, commonly seen on TikTok, Discord, Reddit or X.

big brain means: Very intelligent; genius.. Register: very informal, internet slang. Suitable only for casual conversation, chat and social media. Do not use in business, academic or news writing. A common learner mistake is using the word in a register it does not fit, or assuming a single global meaning; native speakers immediately notice when slang appears in formal contexts, so always check the surrounding register before producing it yourself.

Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.
