Jump Before The Bullet

The most well-known sacrificial move in fiction history.

When someone Jumps Before The Bullet, they throw themselves in front of an incoming projectile attack from an enemy to shield somebody else. Most likely, the selfless act will result in a Sacrificial Death, having the shielded person mourn the passing of their ally they commonly hold closely in their arms. If the jumper can survive the shot for a few moments (and they likely do), they get their Dying Words out before releasing their last breath. It's expected that the shielded person then either cries, yells the jumper's name, and/or becomes a Rage Beast to destroy the enemy and avenge their protector.

Examples of Jump Before The Bullet
American Dad! - West to Mexico. After Stan fires his gun at a group of people, the scene enters Slow-Mo mode and Roger repositions the people to get hit or not get hit by the bullets fired at them. As time resumes, Bullock, after getting hit in the right shoulder, fires his gun at Stan, but Roger Jumps Before The Bullet, shielding Stan. Shortly after, Roger speaks his Dying Words while also revealing that he was a little version of Stan (a Roger with Stan's chin) and dies.

Steven Universe - Together Breakfast [ Justified]. Amethyst enters the temple as a police officer and is about to shoot Steven's abomination of a breakfast with a water gun, but Steven jumps in front of the water spray and saves it. This is Justified as Steven didn't die (let alone get hurt) and the "bullet" is figurative.
