Is "Waiting for Godot" a catch phrase, or what?

Many times throughout act 2, I notice either Estragon asking Vladmir what exactly they're doing in whatever place. And Vladmir responds, more than once, "Waiting for Godot." What purpose does this serve?

why is pozzo so eagerly awaiting Godot's arrival and is there something else behind him going blind?

Why do Vladimir and Estragon continue to ask Lucky for a bone?

Why cant Estragon and Vladimir remember their passed experiences?

And what is the meaning behind this play? Because I honestly have no idea.

Why are Pozzo and Lucky wandering around in circles?

Does anyone believe Pozzo actually went blind?

Why do all of the characters not remember the events that happened in act I?

So....lots of good questions.  Are we getting enough answers?  Are there any answers, really....

Sooo is Godot never coming, and if not what does that reveal exactly?

Were the boots that Gogo found actually replaced?

So I'm gonna be really disappointed not knowing who Godot really is. I hate Pozzo, he's a real bastard. Just sayin.

Miriam's questions and comments

1. What exactly is Estragons and Vladimir's relationship? Are they homosexual or do they just always act irrationally with each other?

2. Who is Godot and why is he portrayed at the "Savior?"

3. Why have Estragon's and Vladimir's attitudes change from Act I to Act II? It seems as if they swapped ways of thinking.

4. Are the characters dreaming or did the actions in both acts really occur?

What is the significance of this "Godot" person? And does he exist? It seems like they are waiting for something that will never come...

Soo do Pozzo and Lucky's ailments in Act II represent the abruptness of life? Also why does Vladimir never want to hear about Estragon's dreams?

In the opening of act II why is estragon so resistant of vladimirs touch and embrace?

If they hate being together why do they keep ending up with each other?

need help!

in at II on page 57(on the other side) who is "they" that pozzo is referring too when he says "...  one day we were born, one day we shall die, the same day, the same second, is that not enough for you? They give birth astride of a grave, the light dreams an instant, then its night once more".

the end of act II

is everything a dream or is vladmir delusional?  what do y'all think.  because pozzo can't remeber anything or anybody .. and he's blind... the boy cant seem to recognize vladimir and the boy also said it's his first time visiting which it isn't ... and even vladmir comes to question himself  if he's even sleeping

So the title of the play was actually the main idea?
