(The complete plot for this South Park Episode)
After a show on TV, metrosexuality becomes a major fad in South Park, among both the men and the boys and they all begin to act effeminate. At the school bus stop, instead of their usual winter clothing, Stan, Cartman, and Kenny wear unmasculine clothing. Kyle, who does not want to conform, is beaten up by a gang at school. Mr. Garrison and Mr. Slave, are opposed to the fad since they feel that their culture should be unique to their kind. The women of the town are initially in favor of their husbands' improved hygiene and willingness to communicate, but soon tire of the men becoming increasingly self-absorbed.Kyle, Mr. Garrison, and Mr. Slave go to New York to eliminate the Fab Five, the hosts of the show who started all this madness in South Park, but their mission fails. They then talk to the insouciant G. stars, who refuse to stop what they are doing. Mr. Garrison demands to know how G. could betray their own people, and then slowly realizes that they are not G. at all. The five suddenly gravely turn to the others and their human bodies burst open, revealing that they are an ancient race of "Crab People".
Captured by these Crab People, who chant "Crab People" repeatedly, Garrison, Mr. Slave and Kyle are unable to stop the crabs from executing their plans of ruling the earth by destroying the human race. However, the wives attack and kill the Crab People. They explain that men need to be masculine and that is what really makes them attractive, even if they are gross. The show producer, discovering that the Fab Five were not human, decides to "bring back the Latin fad" and of course the citizens of South Park slavishly adopt.
At school, Stan, Kenny, and Cartman accept Kyle again, but when he expresses his anger that they previously forsook him, the others call him "G." and go and play football. He walks away in the opposite direction, but then he stops, and as he turns and follows the other boys, mutters, "Goddammit."
