Pity Parties are pasée. A) It's phrasing that just doesn't sound cool. I mean, "Pity Party", "Hissy Fit"... there's nothing positive about phrases like that.
B) Pity? C'mon, we can do better than that. We'd like to propose "Soirée of Frustration". We're not looking down on ourselves at that point. Plus, soirée sounds so much more fun and exotic than a party. It's way more fun to invite people over for a soirée of frustration. There'll be wine and fancy crackers. Maybe even cheese. As Texans, we'd advocate melted cheese. Queso makes everything better.
