Sternwheeler

[Kit]

v. int. The act of pushing ones face in between the [buttcheeks], and rocking ones head side to side very rapidly while making a vigorous, lip-vibrating [brrr] sound. Like a [motorboat], except with the butt rather than the breasts.

[Sommer]

A steamer propelled by a paddle wheel positioned at the stern.

[Luis Fok]

Something you wont find in [Lubbock, Texas], Phoenix, Arizona, most of California, Las Vegas, [Dallas, Texas] or even Winston Salem, NC. You wont find them because there are no sternwheelers to be found there. A [sternwheeler] is not unique enough for you though.
