adj.
Of or pertaining to one who is dressed in a glamorous fashion, as if said person is an indian actress or actor.
When referencing a woman, the word has a positive connotation, as Indian actresses are generally considered very beautiful. When attributed to men on the other hand, the word has a deeply negative and
offensive connotation, as male Indian actors are considered hairy, oddly shaped, and disposed to poor hygienic standards.
Bolly is a shortening of "Bollywood", referring to the hub of the Indian film industry: Bombay (Mumbai), which is commonly referred to as such. This is an obvious play on the word "Hollywood".
This
interpretation is completely unrelated to the British
exclamation, short of "Bollocks".
