Bombay Bol: Ace aka Mumbai’s Finest explains

Chaava
The word refers to a person who excels in everything, dresses to impress, is well-respected and is always on top. In cricket, for instance, there is always that one person who the entire team depends on. So, you would say, ‘Kya khela hai, Virat Kohli; woh toh chaava hai.’ People in my ’hood, in Goregaon and Malad, use it a lot.
