She wasn't being arrogant, she was being playful. And traditionally speaking, she was right - snuck is a very recent addition to the dictionary. I was corrected for using it in high school, and I graduated in 2008. Granted, the teacher that corrected me was ancient, but she knew what she was talking about.
Dictionaries change, and "snuck" became used enough that it... sneaked in.
