What does the "It" In "Just Do It" Mean To You?

I absolutely LOVE <--sarcasm, when I see someone in the gym wearing a Nike shirt displaying the slogan "Just Do It" as I hear them bitch and complain about every little thing. So what does that "IT" mean to you? Does it mean complain like a little bitch? Because if that's the case, congratulations you're doing "IT". I guess that "IT" means something different for everyone but for me it means breaking your ass and giving 100%. So please, refrain from wearing clothing that displays something you clearly aren't capable of doing. Chances are people who take fitness seriously might consider you to be a hypocritical joke. Have a powerful workout everyone!
