Boosie's security prevents a fan from climbing on stage with one swift hand gesture.
Rapper-fan altercations often happen when fans attempt to join the rapper on stage, just think of Action Bronson, and more recently, Afroman. Lil Boosie avoided this exact situation by letting his security take care of the overly eager fan.
During a show in St. Paul, Minnesota, the fan in question was reportedly drunk and acting a fool. He attempted to climb up on stage, however one of Boosie's security quickly intervened and hit him upside the head with a closed fist. TMZ has footage from the interaction, take a look above.
