What are the jimmies that are being rustled?

This rustles my jimmies

seems like a commonly used idiom recently to denote being annoyed, angered, touched. Still, every idiom has some origin, and I wonder what is the original meaning of this one.

Similar to the idiom getting your panties in a bunch, I will hazard a guess that jimmies is a complementary masculine phrase. Jimmies may have originally referred to the male member (or accompanying anatomy). At least one instance occurs in the December 2003 issue of Men's Health.

We put our lives in their hands and our jimmies in their grip.

In the article, "in their grip" refers to wearing a condom.

As for rustle, this definition seems likely:

to act or move with energy or speed

This is just one example of getting your X in a Y or getting your (noun) (verbed) (e.g. getting your titties in a twist, getting your biscuits flipped, and so on). The gist of these expressions is that one is annoyed, angered, or upset. The severity or crudeness of the language may describe the intensity of emotion felt by the "rustled".

Jimmies works as a malleable, polysemic construction. Since it can mean nearly anything, the phrase can be employed in multiple situations, increasing its popularity.

Rustle my jimmies may be referring to the sound chocolate sprinkles make in their box. If so, the Sep 18, 2008 definition provides an etymology of the name jimmies:

Chocolate or rainbow rod-shaped candy on ice cream.

Jimmies were first developed by Just Born Candy Company, which was founded by Samuel Born, who immigrated to the US from Russia around 1910. Born opened a small candy-making and retail store in Brooklyn, N.Y., in 1923. Soon after opening the Brooklyn store, Born invited his brothers-in-law, Irv and Jack Shaffer, to join him in the business. With his capable partners handling the factory and growing sales, Born was free to direct his energies to his many candy-related inventions.

In 1930 James Bartholomew was lucky enough to acquire a job at Just Born, Inc. Bartholomew operated a machine that produced Born's latest invention, tiny hot-dog shaped chocolate sprinkly things. But what to call them? Born briefly pondered that question before deciding to accredit the name to the producer, Jimmy Bartholomew. The new product was named JIMMIES, which is still a trademarked name, but no longer made by Just Born.The dictionary definition for JIMMIES used to be "decorative things." They have also been called toppettes, shots, fancies, trimettes and sprinkles.

When they came to Boston, (circa 1947) Brigham's was the first to promote JIMMIES and did not charge for them. In Boston, JIMMIES are to ice cream like mustard & relish are to a hot dog. Brigham's has continued the long tradition of serving JIMMIES free of charge on ice cream cones and dishes.

A 2009 Snopes article delves into the pre-rustle etymology of jimmies and suggests the Just Born story may at least partly true.
