A method, apparatus, and system of interaction between groups surrounding a present geo-spatial location of a mobile device are disclosed. In one embodiment, a method of a geo-spatial groups server includes verifying a particular user based on a verification code of the particular user placed through a mobile device communicatively coupled to the geo-spatial groups server. The method creates a group tied to geo-spatial vicinity surrounding a current geo-spatial location of the mobile device. The method associates a name identifier to the group and also permits a different user in the geo-spatial vicinity surrounding the current geo-spatial location of the mobile device to access the group. Further, the method automatically denies a requester user access to the group when the requestor user is outside an outer boundary of the geo-spatial vicinity surrounding the current geo-spatial location of the mobile device.
