A woman's vagina is known as a sorting hat when she fucks any man to find the perfect fit
I heard Vicky has a Sorting hat, she has fucked every man at work but not found the right man to Slytherin.

A miserable person. Term comes from the miserable tone of voice the Sorting Hat in Harry Potter uses.
Tom: I don't think we should listen till Christmas music until 2 days before Christmas.

Rebecca: Tom is such a Sorting Hat.
