An empty-headed (and often shallow) person, especially a female. An airhead. Derived from the sound that an empty missle battery made in the '80s Atari arcade game, Missle Command ("doink", "doink", "doink").
Doinkers are fun, kid-powered animated ears. Use a hand controller to activate the movement of soft character ears (either one at a time or both at once) which are attached to a headband. Made by WowWee, award winning toy company best known for Robosapien and PaperJamz.
I want Doinkers bunny ears for Easter! They are made by WowWee and you will be able to find them just about everywhere!
