I think it means "lady killer." Because the song is talking about a girl that was killed 의해 a smooth criminal. just as a side note, according to the Bad25 video when Michael says, "Annie are 당신 ok" it's CPR. The first thing 당신 do before 당신 do CPR on someone 당신 ask if that person is ok 또는 not....and all the dummies Michael practiced on were called Annie!!!
he got the Id for smooth criminal cus in the recoding stode there was a box that had a CPR dummie inside all CPR dummies are named Annie so that's how smooth criminal came about
