I used to see vodka as an innocent "girly" drink as well. Until it became the drink of choice for my EXAG.
I am not sure why - perhaps the fake concept that "you can't smell it on your breath?"
With her it was vodka poured in a 16-oz Diet Coke or Diet Mountain Dew bottle. I've even seen it with McDonalds orange juice at 8 am on a Sunday morning.
