a word for when she has no idea

when jasmine doesnt know what something is, she has a made up word (i presume its made up, cos i have no idea what it could be!) that she uses.

so if you ask her what is this jazz? she will use the word.

and the word, i hear you ask??

"BUN-NA"

shes been using this word for ages. since at least the start of 2010 i think.
