too intimate, too personal

(ねほりはほりきく) Ask nosey questions.
なれなれしい To get in someone’s face that you just met, and take liberties that you would take with a good friend. This includes talking AND physically getting too close. “Wow, that’s a great moustache! *strokes*
くxxx(きやすくxxx) To do something to someone in a blithe, facile manner – too casually, without considering the other person’s feelings.  Like touching a girl’s ass, or telling your friend who just got cancer, “Oh bummer dude, Whelp, you’ll be ok. Gotta skate!”
