Here's a few more, to keep the thread alive:
Arcean to Drengin, first contact
You might think the galaxy is yours, [LISTENING_RACE_LEADER], but you are wrong. Try anything against us, and we will show you just how wrong you are.
So we meet again, [LISTENING_RACE_LEADER]. For your sake, I hope it is for the last time.
Humans to Thalans, Sneer Relationship Very Low
You again? You know, [YourLeaderName], the whole "You Humans are reckless" routine gets old fast. What do you want?
Yor to Torian, Sneer Relationship Very Low
The constant noise you make about your past oppression does not impress us. What do you want?
Humans to Thalans, Sneer Relationship Low
[YourLeaderName]? I hope you are here to do more then simply tell us off for endangering the galaxy.
Drengin to Korath, Sneer Relationship Low
You should have just listened to us on the whole slavelings thing. You would have saved yourself all of this trouble your having.
More to come!
