A particularly useless person whose attempts to contribute in a group effort often hinders or doesn't contribute to the success of the group; ball-trackers fake work to get credit or to avoid of the consequences of doing nothing; originated as a pinball term when there are three people who all want to participate (one right flipper, one left, one ball-tracker who follows the ball with his finger)
"I'll be right flipper, James you're left, and Jacob, if you reallywanna play you can be ball-tracker."
Genetically altered wasps that are coded to attack anyone or anything that disturbs their living. When they make that person a target, they will follow their target until they are stung. Stings from the tracker jacker are extremely painful and cause serious hallucinations. In extreme cases, it cause death. Tracker jacker venom can also be used to hijack a person's memories. The venom creates hallucinations upon the memory and the memory is then seen differently by the person. From The Hunger Games
