River Tits
When a girl take her breasts and caresses it up and down your body until you splooge.
I hope I get lucky with that hot chick tonight and she river tits the fuck outta me. Absolute double-D heaven.
River Tits
The act of slinging ones cock over a females shoulder, then proceeding to urinate over her shoulder between her tits, creating a river of urine through her tits.
After he took her home last night, Søren told me that he gave that girl a set of River Tits with a heavier flow than the Mighty Mississippi.
