Top definition
The necessity and compulsion to share every single fucking thought or emotion with polyamorous partners, for the purpose of avoiding the minor miscommunications or misunderstandings that may not complicate a monogamous relationship, but which may snowball when there are three or more people involved.

Will cause poly relationships to develop at a ridiculous pace, as nothing is ever kept to one's self. Will also seem really, really crazy sometimes.
Omg I'm sorry I was a little distant just now; I was worried I might feel a little neglected eventually, even though I'm not feeling that way at all right now. I was just imagining how it might feel some day. Also, I kind of resent you for that eventuality.

Fuck, that was quite the poly overshare, huh.
