Gash rash is a colloquial term for skin injury to the pubic region caused by abrasion with another person's pubic or facial region, often as a consequence of depilation to said regions hair. Though usually gone unnoticed while attaining gash rash, many find the aftermath to be unpleasant, and even defined by some as excruciating when bodily liquids are introduced to the affected area. It can be avoided by either refraining from shaving, or by epilating (removing hair from its root below the skin) the region instead. One can try to hide their gash rash from being known to others by simply getting dressed, but the awkward stride and stiffled gasps are a tell tale sign of the affected.
The majority of times gash rash only leaves minor abrasions to the skin, that usually disappear within a day or two. Some severe cases of gash rash have been known to take up to 3 weeks to heal, needing a daily regimen of cleaning, drying, and venting of the area until gone.

The female equivalent of road head. A play on the word road rash, but often involving less blood, unless that's what you're into.
I gave (insert female name here) the best road gash on the way home from the movies last night. She was swirving so much she got pulled over
