The use of these emoticons, "o/" and "o7" are actually salutes. With the "o" representing the head, and the "/" or "7" being the arm. The use of these emoticons is used quite often on The Pacific's forums and RMB, with "o/" being used more often than the other. The origin as to which these said emoticons were in use is unknown. It is much easier to understand if you, the user, imagines the salute emoticon as a stick person.
