In her first scene in the extended edition of the film, she introduces herself to Kristen Wiig’s character: “Holtzmann. Virgo. Avid skier. Gluten-full. And a hundred-percent jazzed to meet you.” 

She’s being flirtatious here, but she’s doing it weirdly, like an alien who has picked up on aspects of human behavior—not all of them chosen well—in an effort to impersonate one. McKinnon seems to like this idea. “That’s how I thought of it,” she says with a smile.
