Aaargh plop

From "Can cats spread avian flu?", Nature, Vol 440, 9 March 2006:

Peter Roeder, a consultant for the UN Food and Agriculture Organization, says (Indonesian) locals have an onomatopoeic name for bird flu "that sounds like 'plop', the sound of a chicken hitting the ground when it falls out of a tree. They also have a name for the cat form of avian flu -- 'aaargh plop' -- because cats make a screaming noise before they fall out of the tree."
