The generic name for the girl who was the semi-urban hook up for weird drugs we all knew in high school but didn’t really hang out with. Newports, sweatpants, trauma. The whole package. Picked fights with hall monitors for no reason.
“Yo didn’t Sara Tonin have a kid?” “Sort of. She sold it on marketplace.” “Oh wow ok. Does she know where to get adderall?” “Simple answer: yes.”
