A Jillion

Not a real unit of measure. Often used to exaggerate.

I had to write, like, a jillion-page essay! Due tomorrow!

a jillion

a term used by cool people who don't care that it is not a real term. Used to refer to an exaggerated amount of something when "a million" and "a billion" does not seem to do the vast amount justice. Also see a zillion and a kajillion.

1. OMG! How long has it been, baby? It felt like a jillion years!
2. Trust me, I've done this a jillion times.
