A failure as a man and especially as a potential romantic partner. A man who consistently disappoints and is unreliable. He's not mean or an outright douchebag, but does not meet the most basic requirements one would expect in a man.
He's still whines about his divorce from 5 years ago. He's 40 and doesn't have a job. His cell phone got cut off so he couldn't call to tell me he was running late for our date and he didn't even walk me to the subway after I picked up the tab. He's really nice, but a total maleure.
