To hide, not show yourself. Like famous hide-and-seeker Osama Bin Laden.
1. guy1: "Is John in today?"
guy2: "No, he's pulling an Osama and not showing face."

2. guy1: "ugh, my phone signal's been pulling an Osama all day!"

Get the Pulling an Osama mug.
When a senior citizen that is bed-ridden and not supposed to be alive manages to dissapear from wherever they are regardless of the fact there is a 30 pound machine hooked up to their ass that keeps them from drowning in their own lungs and cant be found by ANYBODY.
God dammit!!! grandpa pulled an osama last night and no one can find him! He took the hemodialysis machine with him too!!
