The Oxford English dictionary has added some words to its online version. One of the more notable ones is beer o'clock. It means simply that it's time for beer. After one has been toiling at work or at a task and one is happily finished for the day, comes a moment of happiness.
"What time is it?" says Frank.
Joe, looking at his watch replies, "It's beer o'clock!"
Later at the tavern, the pair reminisce over the day.
"Boy we almost ran out of sheet rock!' says Frank.
"Well at least there was nothing left over, waste not want not" says Joe after quaffing a few.
"Let me get the next round", the bartender offers.
Suddenly, the mood changes. The door opens and a harried middle aged woman enters, accompanied by two crying children. She speaks to Frank.
"So here you are! You promised to take the kids to bible study and now I'm late for needlepoint!" She hands the whiny children over to the father.
Frank, the wife, and the kids depart the bar.
"Happy beer o'clock!" Joe shouts to his buddy.
