Incest between twins is a subclass of sibling incest and includes both heterosexual and homosexual relationships. While in modern Western European culture, such behaviour is considered taboo and is quite rare, incest between twins is a common feature in Indo-European, Indonesian and Oceanian mythology, and there are a few societies in which the prohibition on it is limited or it is partially accepted.
Agreed. Not only is this entry not encyclopedic, but it's even more poorly written than the main twin article. I nominate this article for deletion. —Preceding unsigned comment added by ( talk ) 23:10, 6 May 2008 (UTC)
