A party, usually attended by women or couples (but almost never just by men, and single men are almost never invited unless they're of the homosexual occasion). It is held at one person's house. That person may or may not be the host. Whomever the host actually is will come to the party with several large plastic bins filled with sex toys, lingerie, lubricants, and oils.
Kind of like a Pampered Chef, Tastefully Simple, or Tupperware party.
Ever since my wife came home with all that stuff from the fuckerware party, she hasn't had sex with me.
