To Ciscoate means to write weird fiction that is genuinely weird.
Most 'weird' fiction isn't very weird at all, but compounded of pre-existing blocks of fairly ordinary and decidedly unweird scenes and situations. The creepy old house, the ghost, the curse, the monster, the twist that isn't a twist, the attempt to evoke a certain atmosphere by using certain descriptive devices. When analysed properly, all are hackneyed and comfortable.
Ciscoesque fiction is different and relies on authentic imagination. It is named after the writer Michael Cisco, the possesser of an outstandingly original imagination.
