Griefer is the term for a player in an online computer game who deliberately sets out to discomfort other players.
A griefer's actions (griefing) include kill stealing, player killing, team killing, stealing dropped items from a kill or during inventory reorganization or a mistake, and general harassment.
For example in MMORPGs (massive(ly) multiplayer online role-playing games), players typically arrive in the virtual world at specific locations. A griefer may lurk nearby and attack the players as they materialise.
In Furcadia and other online games, griefers are often referred to as twinks. This slang term, derived from Twinkie, refers to players who use methods in the game to artificially increase their characters abilities/equipment (for instance, a beginning player wielding a sword that can only be gotten by slaying the most powerful monsters). The term doesn't directly relate to the gay slang usage, but is intended to be similarly derisive.

Although grief and depression do share a number of similar aspects including sleep and appetite disturbances, and intense sadness, these behaviours are only evident for a short time in a grief reaction.
Hence, the expression of grief may be considered unhealthy and demoralising, with the proper action of a friend being to distract the mourner from grief.
By definition complicated bereavement is the intensification of grief to a level such that the person feels overwhelmed, resorts to maladaptive behaviour, or remains interminably in a state of grief without progression of the mourning process towards completion (Worden, 1991).
Our response to loss is varied and researchers have moved away from conventional views of grief (that is, that people move through an orderly and predictable series of responses to loss) to one that considers the wide variety of responses that are influenced by personality, family, culture, and spiritual and religious beliefs and practices.
Grief puts a great stress on the physical body as well as on the psyche, resulting in wear and tear beyond what is normal.
Further, grief is often accompanied by crying, lack of sleep, loss of appetite, and ceasing to care for one's physical and emotional wellbeing.
