When your car is rolling and makes that really high pitched chalkboard noise that causes people on the streets to cover their ears and flee.
Also, when you get a bad shopping cart with the squeaky wheels at your local (insert grocery store name here)
Also, Ridin' squealers.
"That guy that just passed needs to get his breaks replaced or something, cause he is definitely ridin' squeakers."
"I was ridin' squealers when I went to pick up some eggs and bread but was too lazy to get another cart."
