OP
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."

OP
An acronym meaning ON POINT. It just sounds way cooler saying "OP" because "on point" is just so mainstream. It is a word you use in a phrase to compliment someone. If you want insult someone- use NOP.

*Antonym: NOP

GIRL, your outfit is OP. Dude, Kate's booty looks so OP today.
