A rather outspoken individual who likes to broadcast their opinions to the world on the back of their vehicle. They achieve this through the medium of bumper stickers which tend to cover ninety percent or more of their vehicles' backside. They tend to drive the following cars: the Toyota Prius, a Chrysler minivan, or any pickup truck made by GM. In addition to this they do not know the correct use of the passing lane on the highway.

As much as some motorheads love to bash into things, they better hope dat there's always a bumper crop each year, so dat they'll be able to get replacements whenever they need them!

When you are in a bad mood but your significant other wants to engage in sexual intercourse. This is called the grumper bumper because although you're not in the mood, who are you to turn down sex, so you push through with the grumper bumper?
My hoe ass bitch burned my toast, and thought she deserved this dick! She pissed me off so I gave her the grumper bumper.
