I don't know if anybody is still developing this software, but I have a few in mind:
Kill a player with the Max punch => "BITCH SLAPPED"
A bounty has been placed on you => "DEAD MAN" or "WANTED MAN"
Kill a player with a bounty placed on him => "THE GOOD, THE BAD, THE UGLY"
Destroy a Construction building => "MINECRAFT DESTROYER"
