Skittles
In Halo 3, it is the dual-wield of 2 spikers. Originated from the sound the weapon when it is reloaded. It sounds like SKITTLES rattling about in a container. Some victims claim that when killed by skittles, the killer occasionally gun-rapes them and whispers "taste the rainbow" into their ear.
