cuerna de chivo 

'Cuerna de chivo" (KWEARNA dah CHEE-vo) is Spanish for "Ram's horn." This is a nickname for the AK-47 assault rifle, which has a distinctive curved magazine, bringing to mind the curved horns of a male mountain sheep. It is a fully-automatic machine gun under U.S. law.

The AK-47 has many civilian copies ("clones") which are not technically assault rifles, because they are semi-automatic, and are NOT machine guns under U.S. law. They look very similar to actual AK-47's and to compound the confusion, are often called "AK's". And in Mexican Spanish, also called "cuerna de chivos."

"Hey, Pablo, let's go bust some caps with your new cuerna de chivo!"
