diva dart
n.— «When a singer insists that you “take the costume in just a little more” even when it’s skin-tight already, you humor the singer by pinning in the area indicated and not marking it. Then, after the singer leaves, tell the stitcher there are “diva darts” in the shell. They know to simply remove the pins without corresponding marks.» —“Costumer” by Matthew Baldwin Tricks of the Trade Feb. 1, 2005. (source: Double-Tongued Dictionary)
