Any small but dense food item served as an hors d'oeuvres at a wedding; the Spinach Vomit-bomb is the most common type of Assembly-safe Shuriken. Since there are always dozens of these left over when the cocktail hour has expired, mischievous guests load their pockets with them, then fling them at annoying guests - which is hard to spot when in a room with 225 people. Typical victims include annoying mother-in-laws, the guy who showed up in the white tux with a pickle stashed in his underpants, and that annoying aunt who manages to interrupt every dance and photo opportunity to get her ugly flowered dress and $10 Wal-Mart sneakers into the frame.
"Aunt May was being a total douchehound so I pegged that bitch in the head with an Assembly-safe Shuriken. Now they can get the wedding party photos done while she combs crumbs out of her hair for an hour."
