A twelvie bitch is an eleven year old girl who is pretending to be a twelvie, when she isn't even on that level yet, unlike the people the grade above her. She
will have Instagram which she
will update regularly with selfies of her and her BFFL. She has one or two baes and
will beg her parents to drop her at the mall, only to take lots of selfies with her baes and
tag them in the photo. Expect, even in the middle of winter, to have slutty lace tops and miniskirts, and don't forget the make-up! She
will often comment on her friends profiles with a '😍 so pretty bae'. Comes in the form of Ashleys, Georgias, Lanas and Halles.
