To Jeffrey something is to wait until the last possible moment to address a problem, generally waiting until something is /literally/ on fire before dealing with it. Derived from jefferies tubes in Star Trek; small access tunnel routes in starships generally only accessed for emergency repairs.
"Wow, I can't believe Steve would jeffrey it up like that - I don't know how he thinks he'll have it done in time."

"Look, I'm not usually one to jeffrey things, but this week was ROUGH, so screw you for looking down on me for dealing with this now instead of before!"
