The first time I saw this, it took me a bit of time to realize what had happened.
Today, I saw "walla walla". Was completely confused about that until I just googled it now and found there is a song called "Voila Voila".
The fact that "walla" makes sense phonetically, makes it all the more maddening. I have to actually recognize that the dunderheads who made the mistake cannot really be blamed for mis-spelling something they've only heard with no appreciation whatsoever that it's French.
