The word (साला/শালা), romanized as sala/shala is used in both
Hindi and
Bengali. It means brother in-law when used properly. But now the world is also used as an insult or cuss word because it can also imply
incest relations with your sister.
The term was considered super offensive a long time ago but now it's used as normal
slang in everyday vocabulary of native south-asian speakers. It's used in the same context as "bastard" or even "idiot."
