The depressed shit pile (invariably a dude) slumped over at the corner end of the bar when you enter the joint and who is still there when you leave...just more slumped over and depressed by that time. Wants people to ask him what's wrong, especially the cute bartender, but instead should be given a shot of cyanide on the house to end his miserable existence. Mostly likely became a bar-ender after his recent break-up with a hood rat.
"Shit, man, it took you forever to get the drinks."
"I got to close to the bar-ender and he had to tell me his tale of woe..."
"Let me guess; his hole left him for better dick!"
