A bodily fluid drained by working to hard. Symptoms of a low smishnel level would be; a lack of a sense of humor, taking life to seriously or a quickness to anger. Smishnel can only be replaced by doing something you enjoy, such as, spending time with people you enjoy doing something you enjoy. Like, playing golf with your friends, hanging out with your friends, drinking beer with your friends.
My smishnel level feels dangerously low.
I am full of smishnel after the brief visit with the guys.
Luke, feel the smishnel.
