Which Girlfriends character are we describing?

Whodini turned a simple word with a ton of responsibility into a popular song. Another lyric includes, "The ones we can depend on...friends." A real friend is someone who is like an extended family member. You're supposed to be able to trust them, and you all fight like siblings, but the love is always there. 

In the early 2000s, Girlfriends viewers were introduced to Joan, Toni, Maya, and Lynn, four friends in their mid-to-late Twenties in different phases of their lives. They were catty, constantly bickering and straining their friendship until Joan and Toni's ended completely. Oh, and don't forget William, Joan's best friend and the only guy in the group (he also dated Joan and Lynn, an absolute mess). 

While Gen Z and Millennials are nostalgically examining the characters' friendship on social media, let's see if you can guess which one we're describing. 

SIDENOTE: We're also including recurring characters who appeared a handful of times on the show.
