Maybe a reference to Square dancing. “Wooowee!”
“Birdy in the cage and Old Crow out, Now swing your partners round and round, etc
Birdy in a cage is Lady surrounded by dancing pairs, the Old Crow is her partner.
I would suggest that in the Legislative branch square dance
Nancy P is the Birdy and McConnell is the Old Crow. Who is calling this dance I wonder?
The urban dictionary has many listings for ‘crow’, including ‘slut’ and ‘female prostitute’.
