A boomerang made out of ones severed penis.
Wait until you reach climax and decapitate your penis from your body. You can blow into either
end to fill the penis with
air to keep it erect for enough
time to use the Cockerang. Then bend it at as right angle.
You now have your Cockerang... you can throw it at unsuspecting pedestrians for pleasure. If you throw it
hard enough it can climax in mid
air.
The reason it’s a boomerang is because if you do hit someone, there is a very high chance they will return the favour... thus it ‘returns’ to you.
