Very early in the morning. O’Dark-thirty is aviator speak for those bleak, lonely hours between midnight and 05:00 am. Those hours when your brain is telling your body to rest, relax, sleep.

A much classier and more pleasant term (referring to the epic nature of a woman's 30th birthday party) than the commonly used "dirty thirty."

a hypothetical time of day uttered in response to the question of "what time is it." when consumption of said malted beverage becomes an event that is either inevitable or required to proceed with life as we know it in modern society. No other time expression exists with beer in it, ie. there is no beer fifteen, or quarter to beer, there is also not a half past a beer or beer forty five. If it is not exactly beer thirty when someone asks you just say its getting close to beer thirty.
what time is it?

its almost beer thirty.

Half Past Time for a Beer...you're WAY overdue for a cold one and should've started drinking a while ago but weren't able to because you had to finish something up first. When you're finally to the point where you can actually sit down and enjoy a beer that you've earned or need, that's beer thirty.

Well, the work day is over, and it's definitely beer thirty. Any one care to join?
