Puffer Fish 

The act of placing one's mouth on an uncircumcised penis and blowing air into the space between the glans and the foreskin causing it to quickly "puff out" like a puffer fish.

Two things were remarkable when I posed the idea of the "puffer fish" to my girlfriend: First, that she was not only willing, but downright excited to do so. Second, it worked even better that I had hypothesized, and it felt AWESOME.
