A self-appointed Queens parking expert vandalized two cars with spray paint Wednesday, tagging two cars with messages slamming their parking, CBS New York reported.

“Learn to park S bag,” the angry vandal spray painted on the side of a silver car parked in Glendale.

The car’s owner woke up Wednesday to the furious message.

“I know how hard it is to find spots in this neighborhood. So I would try to leave space if there was space,” the woman told CBS. “So it’s like, very upsetting.”

Another car just two blocks away had “Hey scumbag park right” emblazoned in black spray paint on its side and windows.

But neighbors said the targeted cars were parked correctly.

“There was no way another car would have fit there,” Doreen Pratt said.

“A smart car was even too big for it.”
