The sexual act of two partners, the
girl in a position on her back with her legs bent with knees by sides of head. Then the male holds his "dolphin" with one hand and all in one motion, flicks his rist down sending his member into the anus of the
girl.
Soon followed by quickly pulling out the member and repeated several times in a row. This of course can only be performed after performing anal sex prior and loosening up the rectum. Also a recent
slang term in the Adult Film industry for this act.
