Flacidic 

The state of mind a male is forced into, when ALL sexual opertunities, drives and overall mood is diminished in one sudden moment. :(

woman: 'oh yeah baby... uh, give it to me!'
male: 'oh, you like that... yeah!'
woman: *fart*
male: 'oh, JESUS CHRIST... FUCK! im COMPLETLEY flacidic now.'
woman: 'sorry'
male: *storms out, takes a cab home... later has a wank*

flacidity 

The reaction of the male genetalia occuring when open hand contact exceeds a duration of longer than a high-five between two guys while performing the Eiffel tower or any other 3 person maneuver.

My flacidity occured when Brad tried to hold my hand while we were fucking Esther.

Flacidia 

Worse than Erectile Dis-function, Its a never ending struggle with limp ding dong

Girl - "Show me your cack"
Boy - "I can't!"
Girl - "Is your Flacidia acting up again?"
Boy - "......yes"

Flacidia 

A girl who has the power to make any penis immediately flaccid.

I was going hard and then that Flacidia popped into my head and it was over.

INSTANT FLACIDITY 

When your dong is suddenly gone because you were trying to have sex with your sister then your girlfriend walked in. (That word is only a valid word in cases exactly like this)

I was tryna fuck my sister, but bae walked in and my dick got scared so it let out a loud shout saying "INSTANT FLACIDITY!!!" Which of course activated the power to retract immediately so as to flee a dangerous situation

flaccidick

When you have a hard on but become unaroused by something unattractive, nasty, old, smelly, uncalled for, or when a parent walks in on sex with a girl friend, or sessions of masturbation. The penis becomes flaccid so quickly, its as if someone poured acid on it, and dissolved or shrunk it. When you are so turned off you can't get it up, the case is flaccidick.

1.Man last night my girl and i were having sex, and she queefed so loudly, I immediately went flaccidick. I wasn't horny any longer after that, I ended up playing video games the rest of the night.

2. During class i was so horny that i went to the bathroom to masturbate, but someone came into the bathroom and took a smelly shit, and it was hard to concentrate, so i went flaccidick.
