A staple of playgrounds in poor areas, spinamajigs are circular and spin. They are often confused with merry-go-rounds by fucktards who imagine horses everywhere, however, they are completely different in every way.
Person 1: 'Hey, lets go ride the merry-go-round!'
Person 2: 'Do you see any fuckin horses? This is a spinamajig you asshat. '
