A deely bobber (also deeley bobber) is a novelty item of headgear comprising a headband to which are affixed two springy protrusions resembling the antennae of insects or of stereotypical little green men. These "antennae" may be topped with simple plastic shapes or more elaborate and fanciful decorations, such as mini pom poms or light emitting diodes. The name "deely bobber" is a genericized trademark; other names include deely-boppers, bonce boppers, or space boppers. In June 1982, a New York Times headline called them Martian antennae.
