When you see a guy/girl smiling and waving at you at the same time, he/she likely wants to get you dead in a hurry. Especially if it's not a wave goodbye.
First the media said a second wave was coming in the fall. Then they said the United States had already begun a third wave. At some point, they just start saying another wave. They must think it's hilarious.
When you don't want to deal with somebody, don't wave at them, don't make a peace sign with your fingers at them. Quit being a fuckin moron and fucking with their life and their neighborhood.
