I have only few real friends in my life with whom I been growing and went thought a lot of things! I don’t count people with whom I’m chatting on internet or met few times as “bro, or friend” it’s common in American culture but I was born in different culture with different principles! I can’t name such people as a friends! 

 you guys are discussing things based on trust level. maybe need better terms. Acquaintance sounds rubbish. Maybe call anybody friend who you consider that level of closeness required and call the others mates until sufficient time has passed 

 To build a friend is similar as to build family relationship with your wife without having sex with a friend !
