The Boys is a group generally referring to Stan, Kyle, Cartman, and Kenny who appear in almost all episodes of series. The rest of the boys in the 4th Grade are known as the extended gang. They Mostly wait on the Bus Stop.
After Kenny's death, Cartman, Stan and Kyle first replaced him with Butters for the first five episodes. In "Professor Chaos" the boys hold a contest spoofing the Bachelor, and settle on replacing him with Tweek, who lasts until sometime between "Child Abduction is Not Funny" and "A Ladder to Heaven".
During "Bebe's Boobs Destroy Society", Stan, Kyle and Tweek kick Cartman out and replace him with Bebe but this only lasts through the episode itself.
