Clopening is what one does when an erratic work schedule requires that one works until closing time on a given day, and then that they open on the next day. Variations include "Clopen," "Clopener," etc.
Andy: "Man, babe. I really hate my work schedule. They have me closing tonight, and then I open tomorrow. I'll never get any sleep."
Brenz: "Yup, they have you working a Clopening shift!"
In retail closing shifts often end between 9 and midnight and opening shifts start between 7 and 9 am. A clopen is a portmanteau of closing one night and then opening the next morning, thus having as little as eight hours to eat, sleep, and shower between shifts. Depending on the kind of retail and the hours involved, clopens can be a mild annoyance or a brutal test of human endurance.
I'd love to hang out tomorrownight, but I'm clopening, so I won't get home until midnight and then need to be up at six am~
