She probably just made it up. People have their little "terms". I say words that don't make any sense to anyone outside of my family or circle of friends. Like I have a bad habit of saying "Livin like Larry" when Im being silly or saying that I want to live or have a high priced or luxurious item/life style. A lot of people at first look at me like "0_o" but the people I'm friends with get it....Im a Spongebob fan.
