Those are subtly different things.

Griefing is purposefully doing things to ruin someone else's fun, such as blowing up their Minecraft house with explosives or killing them every time they enter a PvP area in WoW. Or quickly killing the enemy that someone needs to complete a quest, over and over before they can. It's not really personal. The "griefer" doesn't have a specific target in mind when they start their run. They just pick someone and do it.

Bullying is more personal. This is someone that has decided they're going to pick on a particular person for some reason. This might be someone they know, or it might be someone doing something they want to stop, like joining a team without knowing what they're doing. Bullying "defaults" is because they don't think the person will know what they're doing and they would rather a teammate that knows the game better. In other games, that might be by player rank/level, attack power, or other means instead of physical appearance.

These 2 things are kind of a hot button for me, obviously.

Hmm, that makes sense. Given that though I would say griefing is a sub-category of bullying then, or a tool used by the bullying party (inheritance vs. composition I guess).
