Intentional (charming?): eye stuff. If you catch me staring from across the room or if I make some sustained eye contact, I'd probably like to sit in your lap. In conversation with a hot guy, I tend to widen my eyes and look up at him, which has proven effective since fifth grade.

If I keep glancing down to look at your lips/neck/shoulders/chest, I probably no longer care what you're talking about, unless it's wrapping my legs around your hips.

I'll probably find excuses to touch you. The only reason I will ever touch someone's hand when they pass me a drink, for example, is if I'd kind of like to see them naked. But it will be an "accidental" grazing of the fingers. I may reach out and touch your hand or wrist while talking, but only if I'm reasonably sure you'd like to see my panties.

Unintentional (weird): my humor tends to get a little meaner and a lot more inappropriate. God help us if there's a straw or pen near me, because I'm going to awkwardly chew on it. Commence mumbling. Should you happen to look back into my upturned eyes with a bit of a smirk, particularly if you're standing very near me, I will giggle unbeffitingly for a woman of my age and status. And I blush, a lot, but more "bright red ears" and less "sexy cheek glow." Combative teasing while smiling - "make me!", "prove it!" - is my invitation for you to please put your tongue in my mouth. As subtle as it is mature.

Really, it's amazing I've ever gotten laid.
