n. System of filesharing popularized after the shutdown of Napster by greedy bigots who failed to realize that the Internet has finally leveled the playing field.
Thousands of P2P networks sprang up after Napster was shut down by the RighteousIndignant Assholes Association.
The instant change in mental state that occurs when one has just finished a wank while watching porn.
You know those moments when you're watching some porn that you think is really hot, then after you 'finish' it all of a sudden becomes completely gross? That's called p2p.
"I was watching a really hot scene, then it all happened, and all of a sudden I felt disgusted at myself and what I was watching! What's that called?"
Paper-2-Paper.
A method of checking one document to another by means of a monotonous tedious task of checking against each other for discrepancies. Used by over-worked employees who have been doing so long they call it a 'P2P' to make it sound more 'street'. These workers are often underpaid, under appreciated, and overlooked while the company banks in excess of 20 million dollars in profit.
This bears striking resemblance to the movie "Office Space".
