I've been subscribing to Merriam Webster's "word of the day" emails for a few years now. Today's word of the day:
\LOOFT-mensh (the “OO” is as in “foot”)\
An impractical contemplative person having no definite business or income.
This is the first word o' the day email that's ever made me say, "hey, I dated that guy."
I wish I'd known the word back then, if only to have something better to call him besides "lazy," "dilettante," or "trustafarian."
