Your brother announces that he got engaged. You're a bit surprised because he has only been dating his fiancee for 5 months. Someone asks what you think about it, and you say:
It kind of took me by surprise.
I feel kind of obligated to go.
You look a little sick. Are you OK?
It's somewhat smaller than I thought it would be.
But only "kind of" sounds right before a verb, and only in casual conversation:
I kind of wanted to go with them.
People sometimes pronounce "kind of" in a way that sounds like "kinda".
This means to surprise someone. It's actually more common to use this expression than to say "it surprised me".
