Universal Serial Bus.
A serial bus standard to connect devices to a host computer. USB was designed to allow many peripherals to be connected using a single standardized interface socket and to improve plug and play capabilities.
Everything today has a USB port and almost every electronic device can connect via USB.
My old computer had 1 usb port at the back. My new computer has 6 and my mouse, printer, iPod, keyboard, external hard drive, digital camera and refrigerator all connect to my computer via USB

Get the USB mug.
A.K.A. Unfinished Sexual Business. The crushing psychological weight which arises when one doesn't use a sexual opportunity to one's full advantage. A kiss is nice, but sometimes it just doesn't cut it and you'll always wonder what could have been. USB is often stronger during a sexual drought.
When it gets to a few months after you last shagged and you're wondering where your next meal's coming from, then you'll get some serious USB, and then I'll remind you how stupid you were to turn that girl down.
