It's Smirnoff Ice, it's the light version of Smirnoff, with a citrus flavor. It's like Breezer which comes in fruity flavors, but the alcohol content of a light beer.
And it's a chick drink in my country as well. But if you're not into the sometimes bitterness of beer, it's a nice alternative because it tastes better. BUT because it tastes better, it drinks faster and they get just as drunk
I went to Club Asia once here in Japan, and Smirnoff Ice was the top drink, everyone drank it there.
