Neighbor hatin' is when a person is playing their stereo, surround sound system, or TV at a high volume level, playing a loud musical instrument, like the drums, or just being extremely loud in general, to the point of disturbing the neighbors. Neighbor hatin' is usually done between 11:30p and 4:30a. Neighbor hatin' can also include, lighting fireworks, throwing a party, or revving the engine of a car or truck with a loud exhaust system.
