funeral damage

In Dungeons & Dragons or similar game, when a player's minimum damage is enough to defeat an enemy but the player desires to see the resulting damage, this is referred to as rolling "funeral damage."

GM: What's the minimum damage for your dagger attack?
Player 1: Let's see, it's dee-four plus eight. So, nine.
Player 2: Don't forget sneak attack.
Player 1: Oh duh. Two dee-six means two more.
GM: Eleven damage is enough to kill this guy. You just need to hit.
Player 1: Woo! Seventeen on the die! Eat it!
GM: Okay, it's dead.
Player 2: Wait a second, you get to roll like, three dice. DO IT.
GM: Fine. Roll funeral damage.
Player 1: Nice! Twenty-one damage.
GM: He only had three hit points left.
