look up any word, like blumpkin:
Dogwin's law. The theorem that as an internet discussion of gay marriage progresses, the chance of someone mentioning marrying one's dog approaches 1. In some online communities, the person invoking the subject automatically forfeits their position in the discussion. After Godwin's Law.
Sprouteater2011: It's only fair that gay people be able to make a lifetime commitment to each other with the same legal benefits.
Dittohead240556: Yeah, well what if someone wants to marry 10 women, or their DOG? You think they should legally do that too?
Sprouteater2011: ~sigh~ You just invoked Dogwin's law.
