OBMG
Original Bitchy Mean Girl. Middle age and elderly peeps who haven’t outgrown the mean girl games of grade school and delight in making a grown woman feel odd person out, reminding her of the mean girls from childhood.
Oh yeah, Aunt Penny is turning 80. One of her kids pissed her off for some petty reason now they’re out of the will. She’s an OBMG. Why can’t she just get over it?
