Young Amata: [after player expresses interest in Christine Kendall] Gross! I didn't even know you liked girls. And you know what I mean, before you say something rude about me.
And so many from SC:
Artanis: What do I look like, an Orc? This is not 'WarCraft in Space'! It's much more sophisticated!
Kerrigan: You know, Admiral, I think I'll just massacre your remaining troops and watch you die in agony. How would that be?
Admiral DuGalle: You vastly underestimate me, my dear.
Kerrigan: I don't think so, Admiral. You see, at this point, I'm pretty much the Queen ***** of the Universe. And not all of your little soldiers or space ships will stand in my way again.
Lt. Sarah Kerrigan: Captain Raynor, I've finished scouting out the area, and... you pig!
Jim Raynor: What! I haven't even said anything to you yet.
Lt. Sarah Kerrigan: Yeah, but you were thinking it.
Jim Raynor: Oh, yeah! you're a telepath.
[referring to the mission]
Jim Raynor: Look, Lets just get on with this, ok?
Siege Tank Pilot: I'm about to drop the hammer, and dispense some indiscriminate justice!
Wraith pilot: You know who the best starfighter in the fleet is? Yours truly. Everybody gotta die sometime, Red.
Tassadar: General Duke, I am Tassadar, and you are well known to me. Whatever leniency I extended to you and your comrades before, may have been in error. If you persist in halting our course, we will burn your pathetic fleet down to the last man.
General Duke: I'm going to have to assume that was a hostile response...
Dropship pilot: In the event of a water landing, YOU may be used as a flotation device
