WHY DO BOYS LIKE SCARING GIRLS?

I have this friend whom I go to certain classes with. Ever since I've posted a status about how much I was scared of the movie, Insidious. He tagged me in pictures of some scary scenes and he commented that he didn't want me to sleep well..andd he was laughing because I got scared.. something like that. We're not enemies. We're not that close. We seldom talk. Now I greeted him and he linked me scary pictures again with evil laughing emoticons. He laughs when I get scared and he really puts an effort in scaring me. WHY DO GUYS LIKE SCARING GIRLS? WHAT DO THEY GET FROM THAT ANYWAY? Just asking.
