Cotton Pontoon

A tampon is a mass of cotton or rayon; or a mixture of the two inserted into a body cavity or wound to absorb bodily fluid. The most common type in daily use (and the topic of the remainder of this article) designed to be inserted into the vagina during menstruation to absorb the flow of menstrual fluid.

Pontooning

The act of motorboating a flat-chested woman with C-cup or smaller breasts.

I went to motorboat that bae but turned out she was wearing a padded bra, so when I got down in there, it was more like pontooning.

Pontoon Boating

Similar to Motor Boating, but accomplished by placing your face in the other persons' ass cheeks instead of their breasts.

My mouth tastes like shit today because I was up all night pontoon boating this girl I met at Starbucks.
