To keep this thread rolling I would also like to add another classic sign that not many know about. If she says that she enjoys writing poetry and it helps her cope and most of her "poems" include the words: girl, when, broken, shattered, heart, and woman then she is a hoe. Here is an example:
A girl stands in front of a broken mirror
Her hand aches
A shattered heart beats in her chest
Dead, just like the glass on the floor
She no longer sees a woman - only a girl
When will she be that woman again?
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
HOE HOE HOE HOE HOE
also any girl that spits off marilyn monroe quotes = ho
ratchet friends = ho
girls that call other girls ho = ho's
wears leggings like their jeans = ho
