Thin privilege* is not having this happen to you:

Having a man come into the store that you work at and come up to you, ask you a question and it with “my beautiful fatty”. Which he then followed with immediately, “but I mean it with the utmost respect, your body size is my favorite and so beautiful”. And then have him not understand why you don’t want to give him your number. Because as a fat chick, I should be honored that anyone is paying attention to me.

Thin privilege is not having your body size as a fetish, and something to be instantly pointed out

*also ties into male privilege
