heart flutters 

The weird feeling of something in your stomach that occurs when someone you’re interested in or very fond of does something. Basically a fancy way of saying stomach butterflies.

“Why are you smiling so much?”

Flutterfly

When a woman lets a fart fly, but instead of punching out the back, it rolls up the front past her vagina; causing her naughty bits to flutter rapidly. Typically caused by impingement due to restrictive yoga pants, or an awkward sitting position. These same harmonic forces destroyed the Tacoma Narrows Bridge in '40.

The combination of that lunch burrito and these yoga pants resulted in a violent afternoon flutterfly; it felt wonderful.

flutterbuy 

Refers to an attractive female's “purchasing” of a mushy-hearted male's compliance/forgiveness/assistance/generosity by giving him a wheedling smile and batting her eyelashes. Often spoken about in a disgusted/sarcastic tone by a fellow male who was not present at the time of said “transaction”, and so he cannot really have any way of knowing for sure if HE HIMSELF might have been hopelessly “melted”, also, if he had been in his buddy's shoes. Daisy Duke is known to be something of an expert at this sort of thing, frequently using her beauty and charm to mellow the otherwise hard-nosed Hazzard County officials and get them to go easier on her two somewhat-reckless cousins.

Recently-arrived museum ticket agent: You mean to tell me that you let that giggle of girls in for FREE?!?!??? Are you outta yer mind, dude?!??

Starry-eyed ticket agent whom he is relieving: Oh, I couldn't help it... they gave me such warm sweet simpery smiles and flapped their long exquisite eyelashes at me in such an alluringly flirty manner that so I just couldn’t bear to charge them anything.

Recently-arrived museum ticket agent: Ahhhh... they pulled the ole' “flutterbuy routine” on you, did they??

Fluttershush 

The act of using ones hands to end a conversation in the manner of shushing a verbal point that is not welcome by the listener. This may also be combined with a verbal low volumne shush.

When I told her I was disappointed, she raised her hands and I got a fluttershush.
