A) the Beatles' first movie that hit the big screens in 1964. Has the same name as the album also released that year.

B) one of Ringo Starr's many idiosyncrasies

C) a cooler way of saying "I've had a tough day."
George: How was your day, then?"
Ringo: rubbish, really. It was a hard days night, you know.

It's been a hard day's night
And I've been working like a dog
It's been a hard day's night
I should be sleeping like a log
But when I get home to you I'll find the things that you do
Will make me feel alright

You know I work all day
To get you money to buy you things
And it's worth it just to hear you say
You're gonna give me everything
So why on earth should I moan, 'cause when I get you alone
You know I feel ok
When I'm home

Everything seems to be right
When I'm home

Feeling you holding me tight, tight, yeah

It's been a hard day's night
And I've been working like a dog
It's been a hard day's night
I should be sleeping like a log
But when I get home to you I'll find the things that you do
Will make me feel alright, oww

So why on earth should I moan, 'cause when I get you alone
You know I feel ok

When I'm home everything seems to be right
When I'm home feeling you holding me tight, tight, yeah

Oh, it's been a hard day's night
And I've been working like a dog

It’s been A Hard Day’s Night
I should be sleeping like a log
But when I get home to you I'll find the things that you do
Will make me feel alright
You know I feel alright
You know I feel alright

A day in which a sporting event takes place and all the senior athletes on that team are starting players. Except for one senior who does nothing wrong and sits all game.
Kid 1 "Do you remember our senior day/night for baseball a few years ago? Kick ass game, so glad we won."
Kid 2 "Oh yeah! I remember that. We all played except for that one kid. Coach must've not gotten the memo about all the seniors playing that day.."

A 'Princess' is an adult woman who is submissive to men they consider to be dominant over them (such as Daddies). The point of being a Princess is the love of being admired, listened to, respected, honored, served, and pampered. The extension of that role is the 'Princess by Day, Slut by Night.' This complementary side of the 'Princess' is when after being completely cared for and treated like royalty by her Dominant, that she willingly becomes a dirty slut to likewise honor in kind whatever her man is in the mood for afterward. Her ability to be the dirty, nasty slut that he loves is dependent on his honoring her wishes and providing for her beforehand.
Her: "I think maybe we should go to fav bistro for lunch... What do you think?"
Him: "Of course my Princess by Day, Slut by night, whatever you're hungry for sounds fantastic."
(later)
Him: "Since the moon is full, maybe we should drive up to the secluded canyon and hike naked up to that one rock that I like to bend you over?"
Her: "Do you want me to paint my tits and ass with that glow-in-the-dark body-paint again?"
Him: "Do it with neon green this time!"

The essence and summary of having lived the 'day' of ones life in 'darkness'. It has been... denotes a looking back or hindsight and the choise of the word 'hard' implies difficulty. Generally such epiphany comes sadly late.

Last minute, enlightenment is frequently found where mill stones were considdered mile stones.
Should you say it's been a hard day's night I will understand
