While many such local dialects have evolved in cosmopolitan cities around the world, Bombay Hindi is widely known throughout India,[citation needed] as a result of its frequent use in Bollywood movies.

[6] Among the more prominent neologisms which originated in Bambaiya Hindi but have spread throughout India are the words bindaas (from Marathi bindhast = without fear, relaxed; this word was incorporated into the Oxford English Dictionary in 2005[7]) and Gandhigiri (coined in the movie Lage Raho Munna Bhai, a combination of Gandhi and -giri, which is similar to the English 'ism' (as in Gandhi-ism, though slightly more informal).
Bollywood has also incorporated many Marathi words in Hindi like weni, thaska, wakda, porgi, navri, navrai, kombdi, mulga/mulgi.
