Incest (A.K.A. Wincest) is a perfectly normal, acceptable and natural act in which two people who are thoroughly related have sexual intercourse. This usually results in children who are very ugly and/or stupid, and in turn, fail at life. Such traits only appear on the first generation and if you have a whole bunch of incest babies then the ones with the defects will die off and it will weed out bad recessive genes and it results in genetically healthier offspring. But this only works if you have a lot, so if you do incest, have as many inborn babies as you can. Incest is one of the key tenets of /b/sexuality (i.e. one of the few things that can make a jaded /b/tard horny after being exposed to so much abstract pr0n), along with rape, pedophilia and gore.

Derived from "win" and "incest".
As opposed to more common forms of incest where abuse is common, wincest must include both sibling and romantic love as well as mutually consensual sex.

As a result, wincest is almost exclusively between brother and sister, and not between parents and children. A related term, twincest, requires that the siblings be born as twins.
Not all incest is wincest, and not all wincest is twincest.

Wincest is win, but twincest is twice the win.

Cousincest can't be wincest because it's not incest.

Win-cest: Referring to the apparently lightly “inbred” nature of the residents of the town of Winchester, CT in particular and to residents of Northeast Litchfield county in general. Cuts across all social and economic boundaries. Might be a Raggy thing, might not. Not surprising really since many of the first families to settle the area are still here after 10 or so generations and have not moved more than a couple miles in the last 250 years. Often used unfairly to target people from Winsted since the populations of the surrounding towns of Colebrook, Riverton, The Hartlands, both East and West, Barkhamsted, New Hartford, Burrville, Winchester Center, Goshen and Norfolk are all at the very least equally lacking in genetic diversity. Let’s not get started on what happens when you cross the state line into the Berkshires of Massachusetts!
She's my 3rd cousin once removed on my mother’s side and my second cousin twice removed on my father’s side. i.e.: a Win-cest uous marriage.

From pretty much any front porch in Litchfield County, if you listen really closely, you can hear dueling banjo music drifting on the wind.
