Brawlsyndrome

Brawl Syndrome is typical of someone who plays or has played Brawlhalla. It describes when they suddenly leave a call or conversation without saying goodbye or any context. This is seen as rude and is similar to how they might leave a game unexpectedly. It can happen at any time during a call.

People with Brawl Syndrome often gather together in new private calls or other places where they can continue their Brawlhalla.

Sorry about Kongsnyd leaving the call so abruptly; he's got Brawlsyndrome from playing too much Brawlhalla.
