A Bang Reaction is a sequence of successive hookups, or bangs, caused by one couple hearing the sexual ruckus of another couple, leading to a series of people going to pound town throughout the house.
Man, did you see what happened in our house last night, Mike and Lucy caused a bang reaction that got me laid, and my other 3 roommates. Thanks Mike!
