The posse during The Stag Convergence

Penny's Posse is the subgroup of a few of the best friends of the Social Group made up of the female members, Penny, Bernadette and Amy. They are the female halves of the relationships that have developed for the male members, Leonard, Sheldon and Howard. The original show dynamics were how the new girl Penny affects the lives of the male members and specifically Leonard's interest and pursuit of Penny.

During season 4, Howard established Bernadette as his permanent girlfriend and Amy became Sheldon's friend who was a girl, but not his girlfriend the Posse began. Bernadette was friends with Penny from working at The Cheesecake Factory together and Amy pushed herself toward Penny claiming her as her best and only friend. Their first night of hanging out together was in "The 21-Second Excitation" while the guys were waiting in line for a re-release of "Raiders of the Lost Ark". Amy was awkward with her interactions with the other two and creeped them out a bit, but gradually they accepted each other and became friends. Penny introduced Amy to new experiences like shopping together, alcohol, trash talking and the emotional aspects of male-female and female-female relationships. The latter experience changed her relationship with Sheldon from her acting just like him to adding experiencing sexual arousal, hand holding, becoming a girlfriend, kissing, Amy and Sheldon telling them that they loved each othe and finally being married. Another strong influence in the Posse was Bernadette choosing Amy for the maid of honor at her wedding after she was hurt when they didn't go dress shopping together. Amy is not against suggesting things that she reads off the internet that women friends do or comforting Penny in a crisis and using her as a subject in her experiments. She also has a limited attraction to Penny and thinks that Bernadette is the least cool of the Posse; however, by seasons 7 and 8 she has became closer with Bernadette since they are fellow scientists. Using the Posse, some episodes have the story lines split down the middle between males and females as they guys follow some geeky pursuit as they have all their lives and the girls hang out in Penny's apartment or have a girls' nights out. The story lines have become much more complicated with parallel plots after the additional of new cast members. They also play hooky and go to Disneyland together and get makeovers as Disney princesses. Most of the time they are hanging out in Penny's apartment, but they have gone to bars, restaurants, a tea parlor, strip clubs and a trip to Las Vegas together. The girls had a habit of helping both Sheldon with problems with life and Raj and his love-life after he lost his selective mutism.

The group was going to Vegas together in season 8 where they partied and got drunk. They also dig up embarrassing moments from their pasts on each other (Amy came up with the idea to watch Penny's movie: Serial Ape-ist 2: Monkey See, Monkey Kill, Penny discovered a video of Bernadette's beauty pageant days and Bernadette blurted out Amy's secret about writing "Little House on the Prairie" fan-fiction about herself and Sheldon).

Near Amy's birthday in season 9, the other girls spilled Sheldon's gift to Amy that he planned to sleep with her. Amy ran out to get waxed.


Girls' night out

In season 10, they took new mother Bernadette out for dancing and go no where wondering if they were trying to recapture their youth. Finally Amy and Penny got depressed because Bernadette had move on further with the marriage than they have (House & Baby).
