Holly Lisle uses it to describe a kind of writing group:
"Sharks and Dinner: Any tightly knit clique that tears apart those not in the Inner Circle. In a Sharks and Dinner group, you’ll notice all the signs of evil in the first meeting or two—people afraid to read their work to others, people speaking viciously of those not present, brutal critiques of works that are read, open hostility toward anything not written in the group’s approved style or genre, people that come to one meeting and never return, and a general Fall of the House of Usher darkness.
"NEVER join a Sharks and Dinner group. Remember, even if they let you be one of the Sharks… when they smell blood in the water, sharks will eat their own."
