arga warga 

The sound of being gobbled up by two mythological dogs, Folleree and Folleroo, from Russell Hoban's excellent "Riddley Walker."

Ful of the Moon Ful of the Moon,
Ful of the Moon nor dont look back
Folleree Folleroo on your track
Oo hoo hoo Yoop yaroo
Folleree Folleroo follering you
If they catch you in the darga,
Arga Warga

argabargabarg 

Term of frustration and discontent, usually spoken in a growling Cookie Monster voice. Commonly used either when something breaks down, or after a period of internally contemplating multiple simultaneous problems all at once and being overwhelmed by them to the point of screaming nonsense.

*smash!*
"Argabargabarg!!!"

(...Intense period of introspection with no definitive resolution...)
"Blah!!! Argabargabarg!!"
