Not exactly sure what it is, but last years rules were: 1. Participants must take at least one drink per hour OR one drink per story (whichever is more often) from the time of their first post; 2. Participants must post at least one story every hour; 3. The story may be of any length or topic, fictional or non-fictional, but horror stories are the overall theme of the night; 4. There will be no restrictions on content, so read at your own risk; 5. The night ends when only one writer is left standing...or sitting...or in any event, writing.
