look up any word, like fleek:
 
1.
Those esthetically unpleasing small round sensors found on many automobile bumpers that provide an audible proximity warning when parking. They almost always look out of place and are not integrated into the overall design of the car and therefor look out of place and ugly... just like a zit on your face. Something you wish you could pop to have them go away and make the car more beautiful.
Oh look, Charlie just got a new Cadillac complete with bumper zits!
