"Bush legs" (Russian: ножки Буша, romanized: nozhki Busha) 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 Soviet Union.
In those times, the USSR was experiencing food shortages and "Bush legs" enjoyed wide popularity.
[1] 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.
[4] In 2010, Russian Chief Sanitary Inspector Nikolay Vlasov banned all chlorinated chicken.
