Background vocals used in film, TV, audio dramas, and other sound productions to give depth to the scene. For instance, people chatting in the background at a restaurant, or the sound of children playing at the park. Basically, the vocal equivalent of extras on screen.
The studio hired extra actors to perform walla to make the mall scene more convincing.

The work many people say / mispell in place of the French word - "voilà" which means (in English) "here it is".

"Walla" is a word used by ignorant people (particularly Americans) who simply don't know any better.
I was looking for my pen and voilà, here it is.

For your information, "retarded American", walla is an actual word. It is on the Scripps National Spelling Bee school spelling bee word list for the 8th grade, and you can look that up right now. Yes, you were just roasted by a 7th grader. But the actual definition is, "A person who is associated with a particular type of work or who performs a specific duty or service." If you're going to make fun of someone, at least check your facts first; if you're not going to you end up sounding stupid.
