Microspeak: who said writing code was fun?
death march
The long, lingering final countdown to a ship date, involving 16-25 hour days, catnaps on couches, and plenty of "flat food" (food, mostly from vending machines, that you can slip under people's doors so they can keep working).
milestone
Semi-technical term for a predetermined point in the product build at which certain goals have been met. Numbered, as in Milestone 1, Milestone 2, etc. Often in reality more like millstones.

They might have told you that writing code was, like, fun and cool and you could do it anywhere you liked and you'd have creative bursts of activity interspersed with spots of surfing, skiing, zen cuisine or meaningful human interaction and so on... Well, forget it, go back to your cubicle and keep at it - if you don't make milestone four, you're toast!
