Baby on board stickers are stickers that you stick to the rear window of a car to indicate there is a baby in there.

the intention of the sticker was to indicate that there is a baby in the car so if the car ends up in an accident, people who see the sticker will take the baby out first as a priority. But no! this cringe that you stick to the rear window of your car makes every driver thinks you are one of these distracted rushing parents that are usually reckless at driving and don't want their insurance going up if they get them selves in an accident, they usually blame the other driver/s because "Baby on Board!" duhhh! Having that sticker on their car which makes the other driver/s the reckless twat/s on the road to them when it is the driver with the Baby on board sticker being the reckless cunt. When we see cars driving on the road with these stickers on, we try to stay away from them as much as possible.
Driver: Look there is a car with a baby on board sticker.

Passenger: stay at a safe distance from them, this driver is a reckless distracted cunt on the road, if he/she causes an accident with you, you will get all the blame because duhhhhh! "Baby on board!".
