A system and method for identifying transient friends for a social network of a user are provided. A transient friend processing function obtains locations of a number of users or locations otherwise associated with the number of users. In order to identify transient friends for a first user, the transient friend processing function identifies other users associated with locations within a proximate area of the first user. For each of the identified users, the transient friend processing function compares a user profile of the first user to a user profile of the identified user to determine whether to add the identified user as a transient friend of the first user. If the transient friend processing function determines that the identified friend is to be added as a transient friend of the first user, the identified friend is then added as a transient friend of the first user.
