Etymology: Sim Racing
1. When, in driving a vehicle (real or virtual), a driver consistently and with incessant fervor, drives the car completely sideways out of every turn, under the mistaken notion that doing so is fast. Such a driver also takes pride in "saving" the car in such situations.
2. When a person feels the need to (and does) post in every single goddamned thread on an internet forum or message board, whether or not they have any contributory input on the topic at hand or not.
