Working with Google's translator, "ovo gun bunda" translates into Spanish as "gun butt Egg" and the English "egg pistol butt" ....... (?)

That is the best I can up with. I am using Google's translator too. If "egg butt pistol" was an English term in common use, something would turn up. Maybe Fernando has a better Portuguese term that I can search for.
