Boo!

In English, "boo!" is the sound you make to scare someone. "Yikes!", the word on our mirror, is a word to show surprise. I think it's funny that "boo" in Japan usually means "car" or "fart". "Meh" in Japanese is what a sheep says. In English, it means "I don't care" or "I'm not impressed". Sometimes even the simplest sounds can be interesting to study in another language!
