Ajai Raj was arrested May 3 during the lecture after asking a lewd question and following it up with obscene hand gestures.
The 19-year-old was hit with misdemeanor disorderly conduct charges after he asked Coulter what she thought "about conservative men that all they do with their wives is f**k them in the a**."
He then ran back to his seat, at the end of the auditorium, feigning masturbation.
A police affidavit notes the lecture was attended by several children under the age of ten.
The arrest came months after a student organization, "La Pieda," marred another campus speech by the conservative commentator.
