What does 给盯背过去 mean in 差点没把人家给盯背过去? The full sentence was more or less: 


  差点没把人家给盯背过去


I was wondering if it was a phrase, or if it just meant that they were staring at the person's back.
I think this means that you are staring at people in a rude way which makes them so uncomfortable that they might want to turn their back at you to avoid eye contact.

the "背" here is not a noun but a action which is performed by the person who is being stared at. Hope this will help.
