Definition: A Gang Bang (or gangbang) is a situation where person, male r female, is having intercourse, either blowjobs or penetrations with many man or women by turns or at the same time.
When a man is the one having sex with many women, it is known as reverse gang bang. Usually, the term has been used indistinctably to refer to women getting raped by many different assailtants, but its getting more and more accepted to just use it to consented sexual behaviour within the sex community.
There is also an especialized sex in group practice known as orgies and sometimes sexual fantasies. It is also a sub-genre of porn movies: "gang bang cumshots", "anal gang bang", "lesbian gang bang", "gang bang with drunk girls" etc.)
There is many evidence that this practice was already known in ancient times, even though they didn't share the same name. For example, Mesalina from the Roman Empire was known for enjoying many gang bangs, and Claudius was accused of it. Even though there are many XXX movies of gang bang since 1980, usually no more than half a dozen or a dozen of men participate.
