Gaylygamy
The definition of gaylygamy is a group of people of two or more, that help each other thru life, whom may or may not live together and whom may or may not raise children together. NO sex is involved, ONLY friendships.
For example. My best friend, whom is a lesbian and is single, adopted two boys. They call me and my partner their uncles, We do everything a parent would do. In turn, when we decide to adopt, she will do everything a parent would do in our children's lives. Gaylygamy. Oh and we say gaylygamy after we say or do anything family or parent related. IE: My friend asks us to watch the boys for a night or pick them up from school. Gaylygamy. Or come over and check on the dogs. Gaylygamy.
