When a pregnant, lesbian woman is simultaneously delivering her child and scissoring with another woman and in the midst of this sexual congress the child is passed into the other woman's vagina and back to the biological mother and so forth, oscillating between the two until one of them achieves climax and whatever that woman says is the child's name henceforth.
"So, Fuckmesideways, how did you get your name?" "Oh, my mother was passing the baby when she had me and unfortunately Barbra won. She always regrets losing because she always thought Kyle was such a lovely name..."
