You know what I did the last time I was at a bar and this conversation came up? After finishing my second pitcher of beer, the first a hef and the second a tasty stout, and the three shots that the bartender gave us for free where I was the only one not chasing their drink this exact discussion came up about how men couldn't drink "girly drinks" or how they would just be embarrassed to be seen drinking one. I'll tell you exactly what I told them: Real men drink what they want because they know what they want, pussies don't drink something they like because other fucktards think it's girly. My following cosmo was delicious by the way.
Don't get me wrong I make fun of people for that shit too, but only because it bothers them. If they weren't so self conscious and needing of people to approve of their drink choice it wouldn't be funny and they wouldn't get made fun of for it nearly as much.
