When driving, the act of steering the wheel from side-to-side very quickly, creating a side-to-side jerking motion of the vehicle. Called so because that is how babies drive when they are given a toy steering weel. Example: Maggie Simpson in the opening of the The Simpsons. Lesser synonym: swang.
"We're on a very wide street with no cars about in a tan Saturn soccer mom station wagon that rides about an inch off the ground--let's do some baby driving."

A Pen Drive is a removable storage device that plugs into a computer's USB port. Small enough to carry on a key ring, Pen Drives are great for transferring photos, music, documents and any other data from one computer to another. Different manufacturers over the years have named their Pen Drives with many different names causing constant confusion.
As a result of this the Pen Drive can also be known as Pocket Drive, Thumb Drive, Jump Drive, USB Flash Drive, USB Flash Memory Drive, USB Key Drive, USB Memory Key and USB Memory Stick among many others!
