Blinker fluid
A prank that parents play on their children when they’re old enough to drive. Blinker fluid/fuel is not real but is a common joke, most shop owners play along or will laugh at you.
“Run down to the auto parts store and get me some blinker fluid”, but when Billy went to the store the managers just laughed at him.
