Dogging is a British euphemism for engaging in sexual acts in a semi-public place (typically a seclued car park or a cinema) or watching others doing so. Frequently, there are more than two participants; group sex and sometimes even gang bangs can occur. Observation is encouraged, thus voyeurism and exhibitionism are closely associated with dogging. The two sets of people involved often meet either randomly or (increasingly) arrange to meet-up beforehand over the Internet.
