Clopening

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!"
