look up any word, like dirty sanchez:
 
23.
OP
1. On forums, refers to the "Original Poster" who started the thread, often with a question.
2. (Loosely) refers to any "other poster" on a thread.
1. Thread title: My next FPQ
...
| The FPQ51200 graphics accelerator is actually disabled in North America.
OP mentioned they were in Germany.

2. Thread title: Why do we follow a 300 year old constitution?
...
|| Hitler was democratically elected
| Are you saying Hitler had the right to do what he did?
Obviously the OP was pointing out that Hitler didn't seize his dictatorship by force, meaning that Democracy alone is not enough to protect people from electing someone bad who will kill them.
