Usman is an act of pulling a "no-call-no-show". When someone is missing in action for a short
period of time, they have pulled an Usman. It could also imply being lazy
and/or unproductive when used properly in context.
Tony: What happened to Debbie today?
Jim: She pulled another Usman.
My bunny rabbit is lazy bum, just sits there all day and likes being pet behind
its ears. Its being Usman.
