Could it be that this is what the phrase was referring to all along?
As most SFTC readers know, six drinks a year is about as lush-y as I get. (Twenty-first birthday: two Diet Cokes.) But I'm wondering if root beer-flavored vodka could put an end to that. Yes, it's a real product. You can check out the other wacky flavors, including -- is this right? -- triple shot espresso vodka, at threeolives.com.
Ah, maybe I'll just have an A&W next time I get a root beer craving. Yeah, that's probably what I'll do. Never mind.
