Re: “Bachiyaan”
actually, when I was in college we(friends) used to use term bacha and bachi.
yeh uska bacha hai. => this guy is a bf of that girl. or this guy has an affair with that girl.
so yes, it is widely acceptable in karachi, but if you are speaking English with your guy and using **kid **he will definitely mind it.
fyi, dont use word tight bachi in family gathering.
it is ok to use it in front of friends.
