Poomerang 

POO-merr-ang. Noun. Primarily used in corporate office environments involving the distribution of poo. Not to be confused with poo that rolls uphill or downhill, the poomerang is poo that is sent but inevitably returns at much higher velocity to its original vendor.

Nathan: "Why are these servers so messed up. The person who put these in must have been really dumb!!!"

Rick: "Uh, dude. You're the one who put them in, and built them wrong. Now go fix it. Poomerang, man."

After you have a bowel movement, and you think everything has gone down, one little piece of poo will come floating back into the bowl. Since it has come back, it is a poo-merang.

In an Australian accent, "Krikey, I thought I was done, but I gotta flush again. I got a poomerang".

Firing a shit out of your ass that wizzes through the air and then returns to you. This is then used as a gift to be used as a play thing for little Austrailian children or any other kind of child that enjoys outdoor play.

Ay mate. Little Jonathan is having a great time with the boomerang I made out of last nights tofu stroganoff. The land down under truly is the greatest place in the univers to play with a pooperang!
