One who lives on a low budget. One who drinks heavily, and often forgets about common priorities in life, in order to party first. One who may be a part of, or fan of Lower Life Form. One who resides in the South. One who believes drinking is a sport, or hobby, and not just a social activity.
"Look at that damn Lowlife, hes been curled up on the bathroom floor for two days."
It could be people who are poor, or it could be people who live like pond scum. Or it could be people who have no values, nor standards compared to people who can afford the paper to write standards and values upon.
Don't worry what that low-life thinks! look where they live, they are nothing but low-life.
Low-life is a person who has not evolved past the level of primordial ooze in the scheme of things. A low-life is an opportunist and has no guilt over doing rotten or heinous things. If they hurt the innocent or the naive of course a low-life will blame their victim for not being as low-life as they are.
Antwan is a low-life for taking advantage of lonely little teenaged girls.
