Sincestill

Sincestill is a term that has emerged in online discourse to describe a specific type of fictional relationship dynamic. It refers to romantic or sexual relationships between characters who are closely related, such as siblings, but where the characters themselves are not aware of this familial connection. The core element of sincestill is the dramatic irony experienced by the audience, who are privy to the incestuous undertones of the relationship that the characters themselves are oblivious to.

This trope often plays on themes of forbidden love and the tension that arises from the characters' genuine affection for one another, juxtaposed with the audience's knowledge of their biological ties. It is important to note that sincestill is a fictional construct explored in creative works and does not endorse or condone actual incestuous relationships, which are harmful and illegal. The term is primarily used in discussions and analyses of media, particularly in fandom communities. The focus is on the dramatic and narrative potential of the unawareness of the characters involved, rather than the actual act or implications of incest. The term itself is a portmanteau, combining "sin" and "incest" with "still," implying a continuation or ongoing state of unawareness.
