From askmen.com:

Sometimes the manliest of men can be emasculated simply by ordering the wrong kind of drink at the bar. Ask the bartender for a Cosmo and the stories you just told your lady friend of your days playing high school football or the time you wrestled a bear will be forgotten faster than you can say, "Can you put a little umbrella in my drink?"

Here are 10 drinks that "real men" never order.

10. A drink with a name you can't pronounce.

9. Malibu and Diet Coke.

8. Fuzzy Navel.

7. Anything that ends in "tini" that's not a martini.

6. "What she's having."

5. Anything that you find very sweet and tasty.

4. Sex on the Beach.

3. Any fruit-flavored malt beverage.

2. Appletini.

1. Cosmopolitan.
