T-Rex Defense
If an awkward girl won't leave you alone, make like Ian Malcolm and stop whatever conversation you were having to freeze like a statue. Her vision is based on movement and she will pass you by for tastier prey, like a T-Rex.
"Kelly from the bar came up to me last night and I couldn't shake her off, I had to utilize the T-Rex Defense in hopes she would move on and attack some lawyer guy on a toilet."
