Sexy 9.0
When you ask a girl for her number and she gives you directions to her bedroom door.

Refers to the behavior attached to the belief that women need to act overly aggressive and sexual in order to attract men (scary, pole-dancing, toys-in-the-drawer assertiveness). A term coined by Glamour magazine's "Jake". 
"Before I even got her name she went Sexy 9.0 and started tearing her clothes off."
