This is the new list:
%1 is the number of kills/quickkills, %2 is the killer's name, and %3 is the dead guy's name
$Slayer::Server::BK::KillSpree4 = "\c3(%1 | Heating up!)";
$Slayer::Server::BK::KillSpree8 = "\c3(%1 | On fire!)";
$Slayer::Server::BK::KillSpree12 = "\c3(%1 | Out of control!)";
$Slayer::Server::BK::KillSpree16 = "\c3(%1 | Running riot!)";
$Slayer::Server::BK::KillSpree20 = "\c3(%1 | On a rampage!)";
$Slayer::Server::BK::KillSpree24 = "\c3(%1 | Slaughtering!!)";
$Slayer::Server::BK::KillSpree28 = "\c3(%1 | Obliteration!)";
$Slayer::Server::BK::KillSpree32 = "\c3(%1 | %3 took it hard)";
$Slayer::Server::BK::KillSpree36 = "\c3(%1 | Reaping souls!)";
$Slayer::Server::BK::KillSpree40 = "\c3(%1 | Head-Hunter!)";
$Slayer::Server::BK::KillSpree44 = "\c3(%1 | %2 is a rampaging walrus!)";
$Slayer::Server::BK::KillSpree48 = "\c3(%1 | Chuck Norris wannabe)";
$Slayer::Server::BK::KillSpree52 = "\c3(%1 | %2 killed the dinosaurs!)";
$Slayer::Server::BK::KillSpree100 = "\c3(%1 | Almost as good as Greek2me!)";
$Slayer::Server::BK::QuickKill2 = "\c3(Double-Kill)";
$Slayer::Server::BK::QuickKill3 = "\c3(Triple-Kill)";
$Slayer::Server::BK::QuickKill4 = "\c3(Quadruple-Kill)";
$Slayer::Server::BK::QuickKill5 = "\c3(Quintuple-Kill)";
$Slayer::Server::BK::QuickKill6 = "\c3(lovetuple-Kill)";
$Slayer::Server::BK::QuickKill7 = "\c3(Septuple-Kill)";
$Slayer::Server::BK::QuickKill8 = "\c3(Octuple-Kill)";
$Slayer::Server::BK::QuickKill9 = "\c3(Nonuple-Kill)";
$Slayer::Server::BK::QuickKill10 = "\c3(Decuple-Kill)";
$Slayer::Server::BK::QuickKill0 = "\c3(Multi-Kill)";
I think the kill sprees might be spaced out too far. Who's gonna get 32 kills?
