(noun) Someone who is such an avid gamer, particularly in network games or MMORPG (Massively Multiplayer Online Role Playing Games) - such a typical
game might be "World of Warcraft".
The term specifically refers to the act of such a gamer keeping a PET Bottle within arm's reach of his gaming computer for use to relieve himself (although it is possible that this
game might be a
female, the limitations of anatomy might make the matter much more complicated for her than simply running to the bathroom).
Such a person is often a very accomplished gamer, having
spent thousands of hours grinding levels to get only the best equipment in his electronic, virtual universe.
However, most
people who have jobs and other normal, day-to-day responsibilities will look upon the PET Bottler as a game addict at best, and a complete
loser at worst.
