The OstrichManeuver is the state of a person burying their head to avoid any given situation, much like an Ostrich covers it's head to avoid danger.
Ostrich's bury their heads based on the simplicity, "if I can't see them, they can't see me". People pulling the Ostrich Maneuver commonly figure the same.
Generally the Ostrich Maneuver is a person's last line of defence, given it's failure rate.
Ted didn't do his homework, so today in Math class, he pulled the Ostrich Maneuver by hiding his head under the desk. Unfortunately his teacher saw his backside up in the air and found him effortlessly.
