Good question with a pretty ambiguous answer for anyone that’d try to answer.
For me it’s a combination of skill, intention, and impact. Like a shaky handed sharpie tag on a bus stop isn’t much of anything, but when it says, “kill your local heroin dealer” that’s impactful. The shaky lines start to show the styling they had intended but can’t capture anymore. I’d call that art even though it was painted over a week later.
Someone cut me off going through an intersection at the bottom of a steep hill and just stopped with his blinker on. So politely, I flashed my brights a couple of times, a bunch of traffic is piling up behind me and cars were swerving and slamming on their brakes to avoid an accident. Tons of honking from everybody who’s pissed at this guy. So, he decides to get out of his car and shout at me about it. “My hazards are on what’s honking gonna accomplish?!” Me: “That’s your turn signal.” Him: “Damn I guess my lights are broken, too. Well you shouldn’t be honking so much!” Me: “I flashed my brights, everybody else you made swerve off the road was honking at you.” Him: “Well your car’s dirty.” Steps away back to his road hazard.
I still regret not laying down on the horn after that insult to my whip’s honor.
