the act of "walloping" a persons facebook wall, or perhaps their myspace wall. typically involves a large group of people, who simultaneously comment on one wall post, event, or activity of one of their friends. the group continues to do so until the notifications for the person being walloped reach about 100. followed by a victorious fist pump by all involved, excluding the individual who was walloped
