Compare with 'Troubled Joe'. Everyone has a Klarth in their life. A tall, dark, handsome man with a crappy past and a bleak outlook. He constantly turns to the bottle, and has a real tongue on him. Your dad might be a Klarth. However, if you ever see him hit your mom, he is not the gentle Klarth, but in fact the unholy 'Womanbeater'.
Geez...Klarth came in at 2 and hasn't left for the past 6 hours. He's on his 29th beer.
