So your fuckin' this chick, right? And you've been with her a few times, so you say, "you know what really turns me on? Sex by a window." And she's like, "okay."
So you start fuckin' her from behind so she's looking out the window, and you slip out a few times, but it's cool, because you get right back in each time. Then in a closet or somewhere, you got a friend erect and all ready to go. So he comes up right beside you and when you slip out this time he slides right in, and she doesn't notice that it's not you. You quietly leave the room and run outside, infront of the the window and walk away; make sure the bitch sees you though.
Megan cheated on me so me and Rob gave her the multiplicity.

Also known as Multiple Systems; Related to Otherkin: People who describe themselves as multiple systems (also known as multiples, multiplicity, plurals, alts, and many other names) take the idea of headmates one step further by believing that they actually have multiple people who make up their multiple personalities. So a person who describes themselves as a multiple system will likely refer to themselves as "they" because they believe they are multiple people. When they are acting as the personality of one of their headmates, they call this "fronting".

Some multiple systems will have headmates who are animals, otherkin people, and, of course, fictional characters. There are also people who believe they have galaxies, nebulae, universes, and other space shit, either in their "headspace" or as an otherkin. So some people will believe they are actually galaxies.
From what we’ve observed on tumblr in the multiplicity community, we’ve noticed that systems whose body or core/host is FAAB (female assigned at birth) tend to have a majority of male headmates, and then the majority of those male headmates tend to be queer in some way.
