I feel like I have been in your shoes on more that one occasion...as for the follow up via facebook...is it a tad bit AFC? Well, maybe...will you likely see her ever again in person? Perhaps not...do you have anything to lose by contacting her? No...do you have a lot to gain if she responds positively to your msg? YES! So why not take a stab...
I think its important to come back at her with something clever / neg tho...
I read this on another thread but it sounded like a great one:
"hey...arent you the girl who eye molested me at the ____ bar last night!? naughty naught

...(then make reference to a funny part of the convo that you had at the bar).....you know you have such a white smile?!"
Just an idea...
