Spot the reference. Used in scary devil monastery to mark the witticism one just uttered as a quote from some work of art or literature, the more obscure the better. Those who know where the reference comes from reply in the form “You are $CHARACTER, and you owe me $ITEM”, where $CHARACTER is a character from the story being referenced and $ITEM is something associated with that character. This acronym is never actually expanded to its proper meaning in the newsgroup; posters instead use obscure expansions, the most common being “slurp the robot”, leading to comments like “I pulled my hair out, but couldn't figure out which robot you're slurping”.
