Bean is the slang term for clitoris. A 'quivering bean' is one which is pulsating in excitement. Would generally happen in times of high sexual tension.
That one nasty licorice jelly belly in the middle of my fruity delightfulness! You know the one!! They come along and ruin an entire handful of jelly belly jelly beans. But have no fear, the kids mix is nigga bean free!!
I don’t like you Nigga bean (as you toss the black jelly belly in the trash)!😂
