When a female student from Yeshiva University excessively gyrates your leg or genitals while avoiding direct penile contact. This occurs when the girl becomes inebriated enough to engage in limited sexual activity without being forced to think of herself as a slut. This phenomenon is extremely painful for the participating male party.
"Shit man, I have the worst case of blue balls"
"Did you hang out with Chana Leah last night"?
"How did you know"?
"She Stern Humped your balls into oblivion"
