A belly bumper is a person who is unmotivated, lazy and/or lacks any sense of completion. A person who possesses this type of behavior can partake in said belly bumping activities.
A belly bump is also the clear act of two belly bumpers uniting!

Next time I see a bumper bitch, I'll slap that fucker's face from my driver's seat as he stares at me in bewilderment with his head through my windshield.
