I like STIFF

I like how it has multiple meanings, good and bad, most of which were
applicable to me, and my friends, this past weekend.

The meaning that sticks today is the most basic, least ambiguous one.
My back is stiff. I spent too much time hunched over my laptop. Too
little sleeping in a lumbar-beneficient manner.

I haven't seen any of SIFF this year, or STIFF either.
