A grudge aka revenge kill afaik is when after respawning, you kill the enemy player who killed you last time. The condition for it being a grudge kill is that he should be the first player you kill just after you respawn. --- "Warriors of fate, you shall dance bravely.

For a revenge kill, I believe you need to be the first person to kill them after you respawn from them killing you. If someone else kills them before you get to them, it's not a revenge kill. I'm pretty sure I read that in the in-game text.
