ofc it doesnt make her a bitch. "basic bitch" is a fixed expression:
Someone who is unflinchingly upholding of the status quo and stereotypes of their gender without even realizing it. She engages in typical, unoriginal behaviors, modes of dress, speech, and likes. She is tragically/laughably unaware of her utter lack of specialness and intrigue. She believers herself to be unique, fly, amazing, and a complete catch, when really she is boring, painfully normal, and par. She believes her experiences to be crazy, wild, and different or somehow more special than everything that everybody else is doing, when really, almost everyone is doing or has done the exact same thing. She is typical and a dime a dozen. There are many subtypes of basicness, such as the basic ratchet, the basic sorority bitch, the basic groupie bitch, the basic I'm-so-Carrie-from-Sex-and-the-City bitch, etc, but ultimately, they all share the common thread of being expendable and unnoteworthy and, in some cases, having absolutely no redeeming qualities.
