When you first start dating a dude, his every little quirk goes under the microscope. Is he a good catch? Is he worth a second date?

Bad Breath
They make every breath product known to man, but if nothing's helping the air that comes out of your dude's mouth whenever it opens, it might be time to move on.

"Gagging on first base is a large problem," said Andrea, 24. "One time I was on a date with a guy, sitting on opposite ends of the couch, and I could smell his breath from where I was sitting. And the worst part, he was chewing gum so I knew there was no hope for him!"

Being a Scrooge
We get that the country is in a recession, and we more than appreciate creative rather than expensive dates these days, but lack of funds doesn't give your man an excuse to forget his manners.

"I respect a guy who's smart with his money, but if he can't even buy me a drink when he invited me out in the first place, there will definitely not be another date," said Sophia, 25. "I know it sounds harsh, and I can support myself, but buying me a drink when we're first getting to know each other is a simple gesture that has a big impact. It shows me that I won't have to worry about him being a cheapskate for the rest of our relationship."

Being a Slacker
There's no bigger turn-off than a guy who has his act together, a great personality, great looks, great sense of humor ... he has everything -- except motivation. You're baffled as to why he'd bring you to his place in his parents' basement; he's baffled as to why you'd even think he wants to move out.

"Nothing is worse than a man who has no ambition in life," said Nicole, 25. "I am a very driven person. I once dated a guy who always put off getting a job. In the end we hardly ever did anything together. I got so fed up that he wasn't making moves to secure a job, no matter what the position, I ended things. And I'm glad I did because he's still unemployed!"
