I have a Baltimore linguistics question. →[More:]In reading
Homicide and watching
The Wire (not at the same time), I've noticed that "shitbird" is presented as the A-bomb of profanity. Like, someone getting called "shitbird" often provokes a restaurant-quality beatdown, unless the shitbird in question is in cuffs or not present.
Now, I've had a long and storied career in cussing, but I've never used or heard "shitbird" in real life. And if it's that devastating, you'd think I would. Is it really a term you'd hear in Baltimore? If so, is it really the worst possible thing you can call someone? Or is it just a dialog tic of David Simon's?
