If the name of the album is Glory, then...

[Alice X]

What was the idea behind #TakeABow? I was almost completely sure that after all of this hashtaging the name would be Take A Bow. 
Is it going to be a single? The name of a revamped Vegas show? Or just random? 

[JustLuvMe]

They're the last words she says in Private Show, and she had the perfume out which is why she was promoting it.

She always has a quote for her perfumes 

[BrittonJeanSpears]

She sings it in Private Show, and it also seems to be the tagline for the scent (like "choose your own destiny" for Radiance).

[Freakkkkshow]

It's her perfume tagline. Where have you been all these time  She only uses it every time she posted about the perfume

[Applejack]

[Outro]
Curtains are closing now
Guess that's the end
Can we go again?
Can we do it all again?
Nah, I'll take a bow
Up, down, run it ‘round
Tasting on my apple pie
Apple pie, satisfy
Laughing

 

[SomeoneGimmeBritney]

It's just a perfume tagline and a lyric from the song.
