bumper sticker, n.All

A Bumper sticker is a shortcut. It's like a little sign that says 'Hey, let's never hang out'.

The Bumper sticker is always an indication that the driver of the car is mentally unstable.

The Bumper sticker is the original social media - Publicly posting things about yourself or your life that nobody else cares about.

The Bumper sticker is a low-commitment tattoo.
