Which term was used to denote the frozen chicken legs quarters from the USA in Russia of 1990s?

"Bush legs" is a prevailing term in the post-Soviet states that denotes chicken leg quarters from the United States.

The expression first appeared in 1990 when Mikhail Gorbachev and George H. W. Bush signed a trade agreement about delivery of frozen chicken leg quarters to the USSR. In those times the USSR was experiencing food shortages and "Bush legs" enjoyed wide popularity.

As of 2006, the United States was the largest supplier of chicken to Russia, with only 55% of purchased chicken being domestically raised, 35% imported from the US, 6% from Brazil, and 4% from other countries, primarily in Europe. In 2005, the Russian and American governments signed an agreement where, until 2009, 74% of the chicken import quota would belong to American suppliers in return for the annual expansion of supplies by 40 thousand metric tons.

White meat is more popular in the US, particularly chicken breast, lowering the cost of exported dark meat like the legs and thighs.

In 2010 Russian Chief Sanitary Inspector banned all chlorinated chicken.
