What a hot girl gives you after you pass by her on the street. When she passes you and then looks back at you for a second look, she is indicating that she's checking you out and maybe interested in meeting you. This also shows that you backscoped her too and thing she's hot.
Dude, that hot chick just totally gave me a backscope! She wants me.

when you pass by a hot girl on the street and she looks back at you, then looks forward, then looks back at you again. (similar to the single 'backscope'). This means that she REALLY likes you.
Dude!!, that hot chick just game me a double backscope! i'm gonna go talk to her.
