Granovetter call these WEAK TIES
Step-by-step explanation:
Weak tie theory is the proposition that acquaintances are likely to be more influential than close friends, particularly in social networks. Weak ties that connect social networks are sometimes called bridges. Absent ties are connections that are expected to exist but do not. According to a study, the more weak ties a person has the happier they feel. Maintaining this network of acquaintances also contributes to one's sense of belonging to a community.
