Octoface
A person with eight different personalities who all fight for attention. They might be a gangsta, a skater, a punk, a jock, a rebel, and every other dumb stereotype you can think of. They switch randomly and it’s annoying as hell.
My cousin has Octoface. One minute he’s crying about his ex, the next he’s screaming at a pizza delivery guy.
At the party, Octoface showed up wearing a hat, a shirt, and a jacket. All three were different styles.
She went from being a total nerd to a total diva in 30 seconds. It was like watching a soap opera.
