Dogging is a British euphemism for engaging in sexual acts in a public or semi-public place or watching others doing so. There may be more than two participants; both group sex and gang banging can be included. As observation is encouraged, voyeurism and exhibitionism are closely associated with dogging.

"Amomaxia" is the act of having sex or making out in a car. It does not necessarily include the exhibitionist or voyeuristic aspects of dogging.
