Someone who hurries from task to task, or makes a problem more important than it actually is. The person is "pinging" like a ball in a pin-ball machine.
The pinger is making uswork overtime to install this computer, even though no one is going to move into this cubicle for another week.
A small round pill that will allow the user to move for hours on end like a functional retard (dance), sweat like a peado at a playground and chew their face off like a munted cannibal then fall in love with a fur peice of clothing.
