Excessively posting random statuses and links on Facebookresulting in friends hiding or deleting you to prevent further viewing.
"Did you see what Mandy posted just now? She's on a rampage!" "No, I was tired of constantly seeing her postitute herself on Facebook, so I hid her from my newsfeed."
A more polite way of saying "slut"; remember that a whore gets paid while a slut does the same work for free.
From SNL parody of Girls:
Jessa: I had sex with a cab driver, alright? It's called being free.
Blerta: You are prostitute?
Jessa: No, it's not prostitution if you don't get paid.
Blerta: You are UNPAID prostitute?!? You are lower than dog!
