What stock character/stereotype/thing does Cab Calloway imitate near the beginning of this 1950s “music video”?

Ever since I first saw this performance of Minnie the Moocher, I've been wondering what that means. He is walking stiffly with his upper body with strange leg movements while "brushing" part of his chest with one hand, the other hand's index finger pointing straight down, culminating in a Michael Jackson-esque leg movement (obviously MJ was inspired by him and not the other way around).

My first thought was that he was imitating a rich man with a monocle or something, but that doesn't seem to hold up.

Is it maybe just supposed to "look funny and unusual"?

Answer 1

This is a style from the '40s. Cab here is emulating a hepcat with how they typically walked. Hepcats were known for wearing Zoot Suits. Please read some of the book The Power of the Zoot: Youth Culture and Resistance During World War II by Luis Alvarez with keywords highlighted.

Also, this style of how young men carried themselves can be seen in this scene ("The Big Bad Wolf") from the Bugs Bunny cartoon movie The Looney, Looney, Looney Bugs Bunny Movie. There were a few cartoons from Looney Tunes devoted to this hepcat culture. This example is just one.

Tom and Jerry also had some cartoons reflecting this culture. Here is The Zoot Cat (1944), showing Tom dressed in a Zoot suit and acting the part.
