A line/lines they never wrote into a script

I had an idea for a good bit of dialogue, that would've worked for an argument scene involving Behkhoff and either Alex or Nikita: After whomever eventually gets ticked off at him and then roar out of anger/frustration, they say, “Sometimes, you can be such a…….” and then they don’t finish the sentence, trying to keep their cool, or be ladylike, then Berkhoff either widens his eyes or raises his eyebrows as if to silently ask, “Yeah?” A what?”. And then they just say to him, “….. it rhymes with Berkhoff”.
