A sexual term used for unprotected sex and ejaculating inside of a girl. Raw Dog Nut Up In. Usually used on sluts you meet at bar/club for a one night stand.
Hey, saw you hitting on that hot chick at the bar last night. Anything happen?
Yeah, went back to her place and gave her the good ole RDNUI. Hope she does not get knocked up!
