I have the game in English (I highly recommend it!) and Ashley does say "Wicked," when you do well. I haven't heard "Lame...," but she is appropriately dismissive of you when you mess up. They did a great job with her character and hit both the loner hikikomori and Wednesday Adams vibes associated with her.
BTW, consider me officially on board as a supporter for Ashley in Smash. I'm a long time lurker here, but I think the stars are aligning for the little witch. Additionally, this thread has been a delight to follow
