Crackship

Moreover, in the more silly venues of fandom, some fans generate "crack ships," or nonsensical couplings, such as sensing chemistry between Bonnie/A Rock.

We carve out little fiefdoms with the common love of a middle-aged actress, and we march up the gangplank to board our favorite crackship.

With rarepairs and crackships, it's the unlikeliness or even impossibility of their coming together that gets you going.
