1) Internet Forums: "Original poster". The creator of the post to which the comment refers.

2) Gaming (both videogaming and tabletop RPG): "Over powered". A character, weapon, ability so strong that the game lacks challenge and becomes mundane.
1) Post: "Hitler was okay, I guess."
Commenter 1: "OMG! That's so offensive!"
Commenter 2: "Stop being butthurt. OP is probably just a troll."

2) Me: "Ugh, this dungeon is so easy! Our team just wiped out that owl-bear with three sneak attacks."
Friend: "Well, it's either because two of us are rouges or because the GM made us OP by having us challenge the harder dungeon first."

Overpowered- usually in video games, there are weapons or tools which are seen by the community as overpowered. Some have special abilities, power or handiness that makes the user superior to the other players, and gives them an advantage.
Call of Duty- World at War:

The MP40 sub-machine gun is seen as OP (overpowered) on the consoles especially with the 'Stopping Power' perk.

Generally any weapon which the gaming community views as overpowered is often called 'OP' in game chat.
