Causing your sexual arousal or physical attraction to dissipate (the sexual analogue to buzzkill or downer.) Literal meaning is "causing to become flaccid", but can also be used more generally to indicate loss of interest.
I was so turned on seeing that hot guy walk in, but his racist comments were totally flaccidating.
Yeah, she was sexy AF but her breath was majorly flaccidating.
beyond awesome - so amazing that upon the sight of this thing or person, you can be sent through an entire conjugal experience from beginning to end. if you are feeling flaccidacious you feel as if you have accomplished a task "in grand fashion", "to the best of your ability", "worked it", "laid the smackdown on it", or "put it to sleep".
the feeling that is produced from any extreme physical or mental endeavor if it results in the positive.
this babe was so flaccidacious that i saw her from across the room, and i was "spent" before we even met.
i've been cramming for a week, i just aced my mid-terms, and i'm feelin' far too flaccidacious to deal with anything that serious.
if you have truly given it all that you can give it, then you may enter into the realm of The Flaccidacious.
or
The Realm of Flaccidaceousness
The man who sits between you and a girl at a party to stop you from hitting on her. The protector of women's chastity. Works better than a condom or pills or both.
