The canon pairing between Noah Puckerman and Rachel Berry. The name itself was made canon when Rachel spoke it in 'Bad Reputation.' The couple only lasted one episode but sparked a huge fan reaction resulting in large amounts of fanfiction, fan videos, manips, and other various fan arts as well as various fansites, RPGs and fan blogs. The fan base is still very large and incredibly active, despite the episode in which the ship originated and ended in (1x08 - Mash Up) having aired on 10/21/09.
