BUMP v. (buhmp) 
- to force upward; raise
To BUMP a thread on Gaia Online forums is to post a reply in order to return it to the top of the list of active threads. This is also called "necroposting", i.e. thread necromancy, or "gravedigging", as old threads are said to be dying or dead. BUMP is sometimes used as a acronym for "Bring Up My Post" or as a recursive acronym "Bump Up My Post" and sometimes "Bring Up My board Please" or "Bring Up My Post count" Also, some people use it as "Boost Up My Post".
Typically, a thread may be bumped after it has received no replies in several days, or when other, perhaps less significant threads have knocked it off the front page. In other instances, bumping is used to keep threads deemed important from falling off a front page. In this case, bumping would not be a breach of netiquette; to the contrary, it may be seen as a necessary if mundane task to be performed. Bumping can be in the form of pictures, or words (i.e. bumps, bump, bumpness)
Entire forums of Gaia Online such as the Chatterbox may be made for such activity to simply gain gold, although many forums such as General Discussion and Minishops Forum may "bump" up a thread to keep it visible for posting activity or to consistently advertise a shop within a forum.
