PDFF 

Post-Divorce Fuck Frenzy: when your divorce finalizes and you're so thirsty you fuck every person you ever met while you were married; generally characterized by low standards and pleasant surprise at how easy it is to get laid these days

You're all depressed now, but wait a few months and you'll be neck deep in poon and on an epic PDFF.
