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.
