When someone doesn't show up (is absent) like they were supposed to because they decided to take "a quick nap" earlier. They are still sleeping.
"Where's Wes? He was supposed to bring the stuff!"
"Bruh, you should know better than to depend on Wes for anything. You know he's always napsent when you need him."
