Boulder Highway Swamp Cooler

On a hot day, when sweat has accumulated down your ass crack, you drop your pants slightly and have someone blow air straight down your cheeks causing an evaporative cooler effect resulting an immediate drop in body temperature.

Tom was getting close to having a heat stroke so he had Tammy hook him up with a Boulder Highway Swamp Cooler to cool him off.

extremely delayed boulder

nart's extremely delayed boulder

One of Nart's most peculiar and dangerous tools is an **extremely delayed boulder**. This boulder, which is typically large and menacing, is not immediately harmful. Instead, its impact is delayed, giving Nart the advantage of surprise. The boulder is often placed in strategic locations where it will eventually roll down a hill, only to strike its targets much later, making it nearly impossible to avoid or predict.
