Who is Misha Vainberg? If the reader interprets him as an example of Mennipean satire, what type(s) of behavior or mindset(s) are being satirized with his character?

Misha is the narrator throughout the story, and identifies as a Secular Jew. He often points to his nose to further emphasize this point when people ask about his background. Although he was born and raised in Russia, he attended a university in America and describes himself as a 'philanthropist'. Misha is noticeably overweight and likes 'gangster rapping' with his friends. By the end of the novel, he has learned to do things on his own, and has become more assertive and responsible for his own actions. He accepts the position of Minister of Multiculturalism in Absurdistan, and decides to leave Nana for Rouenna, vowing to return to New York by whatever means possible.

I will need to look further for information on Mennipean satire.
