OP
Open Pollination
Open Pollination is when a plant is allowed to pollinate openly not under controlled conditions, cleistogamy. Pollination may take place because of bees, wind, insects, or other natural means. Human hands can contribute to open pollination by taking one flower from an OP plant and touching it to the rest of the flowers on the same plant and-or neighboring OP plants. Open Pollination may be used contribute to the biodiversity of a species as it produces more plants with a wide variety of new genetic traits.
1. The cannabis industry in Washington state is an entrepreneur's market right now. It's totally OP.

2. The original plant was an Heirloom from my grandmas greenhouse. Since she gave it to me I've been growing it outside in my garden. It's OP so who knows what might have created since then.

3. I only grow plants that are OP because I don't believe in the proliferation of genetically modified rapeseed.

4. My plants may be OP but my marriage is not!

Op stands for overpowered.
Comic fan 1: I love Cyborg more than the Martian Manhunter!
Comic fan 2: I agree! Martian Manhunter is too OP in my opinion and his origin doesn't work with the knowledge we have on Mars.

OP
Gamer term for "Over Powered". This can refer to a perk, weapon, powerup, ect that a player can use against other players. The perk, weapon, powerup, ect can be referred to "OP" because it has extra abilities or damage that give the player an "unfair" advantage against other players in the game. Some obvious examples of OP are:

-the 2nd set of flares on helicopters in Battlefield 3 before they removed them
-the Modern Warfare 2 UMP45
-the Modern Warfare 3 ACR 6.8
-'Catch Up' in GTA 5 races
-you get the idea
Gamer A: "Hey I just went 45-2 in MW2 with the UMP!"
Gamer B: "Well of course you did, because the UMP is OP".

Raging Gamer: "DUDE HOW DID YOU BEAT ME I WAS AN ENTIRE LAP AHEAD OF YOU!?"
Normal GTAV Player: "Because you left Catch Up on you idiot."

OP
Okay, so I've been seeing this one a lot on things like reddit no sleep and it means Original Poster.

This can be used if someone has re-posted something showing that you are referring to the person who Originally Posted whatever you're posting on.

Commenter 1: I hope OP is okay!

Commenter 2: I hope OP updates soon if they can to tell us what was behind them!
