Oca!
She's a beast. She'll punch you in the face if you say one bad thing about your friend. But she's also a sweetheart when she's not bein' a total nightmare.
Oca! That guy called my friend a faggot! I'm gonna punch him!
Oca! I'm gonna beat that guy up for sayin' I'm ugly.
Oca! She's the best friend ever even though she's a pain in the ass.
