The act of dropping a Battlestar several times the size of a Nimitz-class carrier into the atmosphere and going into freefall whilst launching fighters. The Battlestar then jumps back out into orbit less than 100 feet from the ground, leaving a flaming silhouette in its place and creating a megaginormous thunderclap. Also known as the Husker Hailmary, the Maneuver was patented by Admiral William Adama, one of the greatest TV characters of all time on Battlestar Galactica (best show on television) and was one of the centerpieces of probably the best BSG (best show on television) episodes yet, "Exodus, Part II".
"Dude, the Adama Maneuver is completely infeasible when it comes to physics!"
"STFU n00b! It's BSG (best show on television)! Who cares?"
