Runglish is essentially Russian with a large number of words replaced with Russified English ones. Words for foods rare in Russia but common here are among the most widespread English bits in the Runglish lexicon. So are terms related to technological advances made after the immigrants left their homeland.
Russian Bazaar rightly points out that Runglish is not just taking place in Brighton Beach among the immigrants in America - it is also widespread among Moscow media who use Russified English words like manazher (managers), metroseksualy (metrosexuals), khipstery (hipsters), rekruting (recruiting) and benefiti (benefits).
The Times article also points out that certain Russian words have entered the English language, such as apparatchik, intelligentsia, commissar and samovar. The English influence on Russian among recent immigrants, however, is clearly greater.
