Hello!
I've been reading Rita Hayworth and Shawshank Redemption by Stephen King and I've come across the word  jimmies. Could you please explain to mean what it means. Why this word has been used.

Thank you!

 That sounded suitably important, and Hadley’s chest swelled.  Then he glared around atthe rest of us and hollered, ‘What are you jimmies starin’ at? Move your asses,goddammit!’
