abbrev. "Seventh Day Adventists." A bunch of jew-wannabes. They don't say "Saturday," but call it the "Sabbath," and don't do any work between sundown Friday and sundown Saturday. They don't eat pork either or have sex until they're married, and they run around crying about the end times and how everyone treats them 'cause they're different (duh).
I have to work this Saturday because my SDA coworker can't come into the office and write code, but he can go mountain climbing because that isn't "work." What a fuck.
