There's an apartment building overlooking my curb spot. A while back, a bunch of jock bro types were having a party on their balcony and started yelling out " do a kickflip". I was warmed up, so I did one, and they went absolutely apeshit with joy. They also left me alone after that.
If you can easily do one for someone, it's usually the best option.
In most circumstances, though, people yell that shit when I'm on my way somewhere ( with a backpack on ), so I pretend I don't hear it.
