In the United States, the AKS-74U is often called a "Krinkov". The origin of this term is uncertain. A hypothesis was circulating that the name came from the Mujahideen who supposedly had captured a high-ranking Soviet officer armed with an AKS-74U, and that they had named it after him.

Plus why was the okurok ("cigarette butt," as Russian troops nicknamed it) designed in the first place? The AKS-74U is the work of Russia's most famous weapons designer, Mikhail Kalashnikov.

While most forms of gambling are illegal in Japan, pachinko is an accepted legal form of gambling. You have to be 20 to play, but there are no other conditions.

A government survey last year found that 3.6 percent of Japanese have been addicted to gambling at some point, higher than the 1-2 percent average in other developed countries, and that pachinko was the top destination for gamblers.
