A deely bobber (also deeley bobber or deeley bopper)[1] is a novelty item of headgear comprising a headband to which are affixed two springy protrusions resembling the antennae of insects.[1] 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;[2] other names include deely-boppers,[3] bonce boppers, head boppers, or space boppers. The product was introduced in 1981 and quickly became a fad of the 1980s. In June 1982, a headline of The New York Times called them Martian antennae.[4]
