look up any word, like bootylicious:
1. tweak the bean
1) When a girl masturbates by exposing her clitoris with two fingers, and rubbing it with a third finger.

2) Clitoral stimulation
"Dancing with those guys really got me worked-up! I am going home to tweak the bean!"

or:

"Dude, it's so easy to give her an earthshaking nut! Just be sure to tweak the bean, and she'll cum all over the place!"
