Mischievous Girl

Walk by a hot girl who’s standing/sitting by herself or slightly away from her group of friends, and deliver this over the shoulder:

You: “So why are you standing/sitting there trying to look mysterious?”

Her: (smiling) blah blah

You: “Yeah, see… you got that mischievous look on your face like you just did something bad and got away with it”

She should be smiling and laughing by then if delivered right.
