Originally, ventriloquism was a religious practice. The name comes from the Latin for to speak from the stomach, i.e. venter (belly) and loqui (speak). The Greeks called this gastromancy. The noises produced by the stomach were thought to be the voices of the unliving, who took up residence in the stomach of the ventriloquist. The ventriloquist would then interpret the sounds, as they were thought to be able to speak to the dead, as well as foretell the future (source: Wikipedia).
In SL you could say we're all more or less ventriloquists because we let our dummy (pixel doll) do the talking for us. However, this picture shows a clear example of the real Dummy Ventriloquism Syndrome in SL and I have only seen it once so far. This ventroloquist is taking it very literal and wants his dummy to put another dummy up in the stomach to let it do the talking for him. That really shows that this is a stupid person and has no common sense and no brain at all. A real dummy !
P.S.
Don't mistake this kind of dummy with the typical Baltimore girl that will suck anybody's dick, or have sex with them. Source: Urban Dictionary http://www.urbandictionary.com/define.php?term=dummy
