you pick a guy who is the worst person ever, and you yell "look at that douche bag!" so loud that the sky might fall and the world might end
I did it in the grocery store when the guy was arguing with the cashier about the price of one bread
At the gas station, I yelled it so loud the gas pump started leaking
I did it in the park when the guy was feeding ducks and yelling at them like they were his enemies
