It usually referred to as, Shuttle Bump Baby. It is only valid for those who are in 'RELATIONSHIP' and used to make your partner horny. It came from a structural design called, BUMP, which we usually find on the roads of Asian countries and is made to control the speed of the vehicles.
I know it sounds weird. But, it works. Try to go over the bump if you find near your house and comment your experience. I am damn sure you will enjoy it.
Jamie: Dad, I wanna go over the SBB!
Dad: What's that, baby?
Jamie: Dad, it is called Shuttle Bump Baby, the bumps we usually see on the roads to control the speed of the vehicles.
