A woman who is horny and wants a good hard screwing has the “jelly roll blues”. The jelly roll is the vagina and it has the blues for some satisfaction.
Girlfriend- “I’ve had a serious case of the jelly roll blues since my boyfriend has been out of town. I can’t wait until he gets back and gives my pussy the attention it deserves.”
A "jelly roll box " is usually a stainless steel or aluminum box affixed to the wall next to toilets in public restrooms. The jelly roll box is provided for women to dispose of their used sanitary napkins or tampons in rather than to flush them down the toilet.
