Pagong (puh-gong) - v. to systematically remove members of the opposing tribe before eating your own.This technique was devised by Rich and the evil Tagi alliance in S1. The Tagi tribe decided at the merge to vote off each member of the Pagong tribe one by one until there were only Tagi members left. 4 of the 5 Tagi tribe members voted in this fashion at this fashion. (And Sean decided that the Alphabet strategy was his key to not having to vote as part of the "evil" block of 4 and make people mad.)
Since S1, most Survivor installments have involved some variation on the theme of Pagong. The best installments have actually drifted away from Pagoning, such as S6 and S7 when tribes got shuffled around enough that tribe loyalty was not as important as simply surviving for one more tribal council.
Games where Pagong played a major impact: S1, S2, S3, S4, S5
These also got boring after the second round, though having to live off the land without the rice ration was a fun change in S4.
Games where Pagoning never really took place: S6, S7 (see above)
Game where Pagong is just as boring as before: S8
