"POK" is the infamous sound made by a tennis ball coming in contact with a perfectly placed swing of a tennis raquet.
POK is also the term given to ThumbDrives or USB Drives (USB Mass storage devices).
This term is derived from the brand name of Hewlett-Packard USB Drives called the "PockiDrive".
Shortened, edited and combined with the personified "POK" sound, the term "POK" took over the old USB(Thumb)Drive.

PoK is an acronym used by the players of the MMORPG Everquest, in order to easily refer to the Plane of Knowledge. This is a zone that was introduced to the game in the expansion set, Everquest: Planes of Power, which coincidentally enough, users of Everquest often refer to as PoP.

The Plane of Knowledge is a central area to the game, in which people may access distant places all throughout the game world, via clickable stone portals placed throughout the zone. Thus, it is spoken of a lot while playing.
