Savage was partying it up Saturday at an annual rager in the Atlanta area called "Big Ass Pool Party," when a large group of people crashed the event through the back.
Eyewitnesses told TMZ, Sav appeared uneasy at the unexpected entrance, and that all hell broke loose when a person from the other camp said hi to a girl in Savage's circle, upsetting his side. We're told someone from the crashers' crew pulled out a gun when confronted, which led to Savage arming himself, too. It appears he receives a revolver from a friend.
No shots were fired during the altercation, but someone from the invading group was hit to the ground. Cops eventually shut things down -- no word on any arrests.
