A flat curved airfoil that spins about an axis perpendicular to the direction of flight, originally used in various parts of the world as a hunting weapon or, in returnable types, for sports or training.
Some resemblance to terrestrial things, it is true, everyone can behold in the heavens. Corona, for example, is like a crown, or, as the Australian black fellows know, it is like a boomerang, and we can understand why they give it the name of that curious curved missile.
With boomerang and spear they hunted the kangaroo and emu, and fought their battles beneath the eucalyptus forests; their minds, fresh, untroubled, contented, oblivious alike of noble ideals and philosophic principles.
1961, Charlie Drake, song, My Boomerang Won't Come Back,
"Don't worry, boy, I know the trick, / And to you I'm gonna show it. / If you want your boomerang to come back, / Well first you've got to... throw it."
A breakdancingmove in which the performer walks on their hands while keeping the legs raised off the ground.

2013, John Holloway, Illustrated Theatre Production Guide, page 144:

"Well, there must be some flaw about this," I suggested. "If your magnet is so strong as all that, you would have your own broadside boomeranging back upon you."
"Oh," they yelled, "you could, eh? Well, let's see you do it, then! Let's see you do it! Let's see you do it! Now!" In a moment the crew of little spectators were gibing at Horace. The blow that would make Jimmie's humiliation complete! Instead, it had boomeranged Horace into the mud.
Our future economic success depends on the economy growing faster than government spending. That's why raising taxes would boomerang. Economic growth would slow, revenues would decline, and the budget deficit would swell.
