If we say it
literally then it means Sisterfucker but if we look in daily conversation then it is sort of expression. for example - Excitement - Ohh Bhenchod i won !!, for showing anger (now it become
rude and offensive) "Bhenchod i will rip you apart", for showing frustration "i got screwed... bhenchod !" feeling surprised "bhenchod !!!!" and it can be used in many more situations. This word is slang and generally used between friends and in same age level group, it will be considered offensive and
rude if used in front of elders, relatives and in conversation with unknown
people. It is like word "Cunt" in England, it is acceptable there but if you say cunt in USA then it will be taken as offensive.
We can also use it wherever we want, like - I was going at high
speed and bhanchod out of nowhere suddenly a dog came in
front of my
car, bhanchod ! i applied brake immediately and that dog was saved by an inch.
