Eagle rock
1 – a popular black dance from the 1920’s, performed with the arms outstretched with wings and the body rocking from side to side. Here’s a description of the Eagle Rock (Ballin’ The Jack ?)dance:
"First you put your two knees close up tight, then you sway ’em to the left
Then you sway ’em to the right, step around the floor kind of nice and light
Then you twist around and twist around with all your might,
Stretch your lovin’ arms straight out into space,
then you do the Eagle Rock with style and grace.
Swing your foot way ’round then bring it back.
Now that’s what I call Ballin’ the Jack." from http://ift.tt/1hsIxbG ]
[some say Eagle Rock is a metaphor for sexual congress, but I have no special insight into that usage in re: this photo]
I only knew the phrase from a Blind Willie McTell song, Kind Mama:
Soon in the morning at half past four
Hot shot rider rappin’ at her door
She’s a real kind mama looking for another man
She ain’t got nobody in town to hold her hand
Went to the door and the door was locked
Think that baby tryin’ to eagle rock
She’s a real kind mama looking for another man
Real kind mama looking for another man
And she ain’t got nobody here to hold her hand
Kind mama looking for another man
