"Brian Tumor" (noun): A highly contagious and profoundly debilitating condition primarily affecting pre-adolescent males named Brian, typically observed at age 12. The disease manifests as an uncontrollable expansion of ego and a dramatic increase in the frequency of unsolicited, poorly timed, and often cringe-worthy attempts at humor. Symptoms include a marked decline in tolerance for other people’s well-being, an overwhelming need to insert oneself into every conversation, and an alarming tendency to dominate social situations with an incessant stream of 'inappropriate' jokes.When you're stuck in a group chat with a 12-year-old named Brian, and he won't stop making terrible puns, interrupting every conversation, and somehow turning everything into his personal highlight reel. It's like his brain is a tumor, growing uncontrollably, with zero regard for anyone else's sanity
Bro, I can't take it anymore. Every time Brian speaks, it's like a Brian tumor of bad jokes and unsolicited opinions. Someone please save us.
