Quiz of the Day

This is for all you English geeks (and wannabe English geeks) out there.

I present two words to you that I've actually seen (or heard) used. It's your job to create an appropriate and thorough definition of either/both. Feel free to whip up multiple definitions. I'll post the consensus voting in a few days.

1. portentious

2. mannifactured

You may open your books and begin.
