I have just noticed that Beyonce has an album with this title.

I use it as shorthand for “birthday.” I have no idea if that’s how Beyonce is using the term.

I wouldn’t be surprised if it was intended to mean “Beyonce Day”.

You think it’s a pun on bidet ?

5

Australian for “have a bad day”?

The album was intended to be released on her 25th birthday. Cite So I think both the birthday and the play on her first initial meanings apply.
