Definition: Surprising! Imagine being introduced to a person who is so unpredictable that you can't even predict their future behavior. They will surprise you by surprising your deepest fears and letting you know they are as good at making people uncomfortable as they are at charming you.
Example: "I've always admired the way she surprises me with her latest perfume. Every time I wear it, my heart skips a beat because it makes me feel like I'm in some kind of dreamland."
