I think the way it's phrased and in light of the use of the term "gay" to be negative with young people about 5 years ago (many of which are now legal drinking age) the term "gay" here means tainted, less cool than drinking it straight. I interpret the subtext as: "Sure you can drink it with mixers, but that's GAY - if you're cool, drink it straight."

You'd think that in an ad that is accepting of homosexuals, they'd leave out an arrow that points from the bottle to the words "Drink straight."
