ratting
n.— «It can also cause some performance slowdowns in low-security areas where players are staging large fleet battles against each other. But for people who may just be “ratting” (a term for fighting small skirmishes with computer-controlled opponents) or going on mining runs, this really isn’t that much of an issue.» —“EVE Online” by Peter Cohen Macworld Dec. 31, 2007.
