Nelly was not having it when he was partying at a club in Miami and was hit in the head with something.
In the video you see Nelly hanging out when an object (maybe and ice cube) was thrown from the balcony by someone. Nelly looks up and then is immediately triggered and charges toward the balcony.
Nelly's entourage, along with security was able to stop and deescalate the situation.
