If you do that, you failed the test. People who use inside jargony things love to explain them, and love to be asked what they mean. Also, they can usually tell when you don't pick up on it.
When I interview someone I'll throw in something company specific, that I know they won't understand, just to see if they'll ask me what I meant. I don't want to work with someone that is afraid to admit they don't know something.
