Question

FUH2.com is a photo blog where people submit pictures of themselves giving the finger to H2 Hummers.

Answer 1

The H2 hummer is the model of Hummer's second commercially released sports utility vehicle. The original hummer was built for use by the US military, and later released commercially as a private vehicle. Hummer makes three vehicles, the H1 (the original military vehicle), and the H2 and H3, which are redesigned to be more appealing to the civilian market.

The H2 is also available as the "H2O", an H2 SUV with a hydrogen-cell engine.
