someone that blinks uncontrollably so that his vision turns into a sideshow. This sometimes leads to awkward moments and situations where the person misses something in life which is why most Blinkys are mentally impaired/ retarded.
Yesterday Kelvin started touching men, but then i remembered that he was a blinky and i took pity on him because he couldn't see and was mentally retarded.
If you someone know who is cool, funny, and an all around good person, their name can be substituted for the word "Blinky". Blinx or Blinko or Blinkmeister are also appropriate. As a matter of fact, any variation containing 'blink' in it is fine.
Blinky's on fire! He just gave that girl the shocker!
