"Boynapped" in the context of gay porn refers to a specific sub-genre where younger or teenage boys are involved in sexual activities, often involving forced or non-consensual encounters. In this case, it signifies a video that may depict a storyline where one boy is captivated or kidnapped by another, and as a result, engaged in gay sexual activity against their will (or at least the pretense of lack of consent). Note that this description refers to fantasy content and not actual child abuse.
