I don't get a particularly gay vibe off of them...just that they're joking around and making a ridiculous music video to a ridiculous song. It's possible, though. What do I know, eh?
someone else put it nicely: "Guys in speedos dancing while being admired by a group of other guys...Yes, it can be seen as just heterosexual horseplay or male bonding. It could also be read as homoerotic."
i would replace the word dancing with penis wiggling tho
