An exclamation of surprised incredulosity in (usually) a teen's first observation of an animal, human/animal, or human adult sexual act , usually of the non-missionary position variety, or a teen's first observation of anything especially surprising to that teen. Appropriate only to instances of truly juvenile pre-teen or early teenage humor. Implied connections to non-heterosexuality, ethnicity, sex, and dogs seem obvious but somewhat oblivious to the teen.
On seeing, for the first time, a human milk a dog, or on seeing a bull mate with a cow, or on being unusually surprised by anything, a teen exclaims "gaywopfogdog!"
