Not to be confused with hellish, healish is English slang derived from the word heale, it is an adjective used to describe someone whose behaviour is that of a total tosser, waste of space or OIC. They are the sort of people for whom arsehole is too kind a name, who are narcissistic crawlers with little in the way of either intelligence or talent. Avoid them at all costs as their proximity will bring on attacks of acute nausea.
