Failure Rate: unknown
Turns Off: chicks who don't like KE$HA and chicks who just aren't into you
Requirements: being in Vegas and a lot of alcohol
Prep Time: however long it takes for you to get drunk
Upside: if she likes you, you're probably gonna get lucky
THE PLAY: Go to Vegas, drink a lot of alcohol, blackout, wake up the next morning to find out that you drunk texted "your love is my drug" to some chick that you want to bang. Announce this to your buddies. Have them laugh at you. Damage control.
