What is Sector 7-g!?
1.
An exclamation used when something's gone mildly wrong - based on the idea that Homer Simpson works in Sector 7-G at the Springfield Nuclear Power Plant and is always causing crises.
Colleague one: Sector 7-G!
Colleague two: What!? What!?
Colleague one: Dude, I totally just accidentally forwarded all that scathing correspondence to that arsehole in sales.
