Rash

adj. reckless, hasty, impetuous

n. inflammation or eruption on the skin; large number of unexpected events

A rash is a change in skin which affects its color, appearance, or texture. A rash may be localized to one part of the body, or affect all the skin. Rashes may cause the skin to change color, itch, become warm, bumpy, dry, cracked or blistered, swell and may be painful. The causes, and therefore treatments for rashes, vary widely. Diagnosis must take into account such things as the appearance of the rash, other symptoms, what the patient may have been exposed to, occupation, and occurrence in family members.

Red and Anarchist Skinheads (RASH) is a left-wing anti-racist, anti-fascist skinhead group. RASH includes redskins and anarchist skinheads. It was officially launched on January 1, 1993 by members of the Mayday Crew, a left-wing skinhead and punk group based in the New York City area. The Mayday Crew was formed due to in-fighting between members of New York City's Skinheads Against Racial Prejudice chapter, over the murder of a homosexual man by anti-racist, yet right-wing, skinheads.
