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!

Stands for Original Prankster.
I posted pictures of platypuses all over campus, so I shall now be addressed as "THE OP".

Stands for Original Pirate. These are the elites of the gangsta pirates, who cruise the oceans with gats in hand, searching for booty. The most famous gangsta pirate set is the POP (pirates of the pacific). They are headed by O.P. Captain Morgan and O.P. BIG Pirate. They have been mostly interested in getting drunk and high, but as long as they have a designated sailor, they will control the rum and marijuana trade of the pacific ocean. O.P. for life!
Yo homes, we just got done with a sail-by. Yeah, foo, that Atlantic O.P. wont be slangin' no more rum in these waters. ARGHHHHH

Organic Portals, or "O.P.s", are quite simply soulless organic robots that pass as humans in the everyday world. O.P.s are remarkably efficient, quite common, and can be found at home, in the workplace, or generally anywhere that genuine souled humans are found. O.P.s are completely incapable of generating emotional energy for themselves, so they feed off the emotional energy of souled humans. O.P.s are apparently indifferent as to whether the emotional energy is positive or negative in nature, and appear to assimilate both with equal ease. O.P.s can often be identified while taking repeated actions which hurt you and other people that the O.P. supposedly cares about. When asked about their behavior, an O.P. will provide a completely incoherent explanation for their actions, and then promptly continue repeating the same actions as if nothing had happened. O.P.s do appear to have some limited capacity for learning. Experienced O.P.s have been observed to delay immediate gratification in favor of orchestrating one large dramatic event in which they can extract a large amount of emotion from you and a number of others all at the same time.
Example 1: I should have realized that she was an O.P. after the second time she cheated on me, but she charmed me right back into denial.

Example 2: I can't believe that freeking O.P. had the nerve to bitch to my boss about me right after telling me to my face how much she enjoyed working with me.

Example 3: The O.P.s said I have to be home by midnight.

Example 4: I am -so- sorry I ever had a child with that O.P.

Example 5: I am -so- sorry I ever loaned money to that O.P.

Example 6: Don't let that O.P. get you down.

Example 7: Can you believe it? That O.P. actually took responsibility for something!

Example 8: In business news, O.P. Inc. was purchased by O.P. Bank.

Example 9: Normally I would be against the death penalty, but that O.P. should fry.

Example 10: Stop acting like an O.P. and show some goddam emotion already!
