1. The spirit of irony and fun. You recognize it’s hilarity and are employing it for the sake of comedy. You’ll often deliver this through the windshield of your car towards a friend as you pick them up or drop them off. It’s a friendly greeting.
2. The spirit of sincere anger and malice. You’re so overcome by rage that you have no other recourse but to resort to a ridiculous hand gesture. You’ll often deliver this through the windshield of your car towards a fellow motorist when merely swearing at them just doesn’t feel like it’s enough.
Regardless of your intention, it’s cool because you’ve chosen to focus all your emotion into the tip of your middle finger. And hey, there’s nothing quite as satisfying as letting someone know they’re Number #1.
