When talking to multiple persons on AIM, you confuse one buddy's blinking window with another's...Thus creating a blinky mixup. Used most frequently when one conversation is extremely important, and one is more relaxed and carefree. The important one being the one that did not blink, and the carefree one being the one that did.
