the act of a female when spooning with a male, the female then positions her ass directly in alignment with the male's dick. this is usually practiced as a full proof technique to initiate sex, especially when the male is oblivious to her previous advances.
"After suffering through 3 hours of tivo'd Entourage I slipped him the assdick and we were sexin it in no time."
