A PasteBin is a site that allows one to paste chunks of code or text. The snippet is given a unique URL that may or may not be permanent; some advertise new pastes to IRC via one or more in-channel bots.

It is considered good etiquette to paste code or text into a PasteBin rather than directly into IRC to avoid interrupting conversation, to facilitate versioning, and to make it easy for people wanting to reconstruct test cases to copy and paste code without removing extraneous text inserted by IRC clients.
