Flacibo 

When an erection seems to be present but upon further investigation, the realization of a flacid penis presents itself.

After watching a cops marathon I thought it was time to jiggle the ole cream noodle, but realized my erection was just a flacido.

"Is that a banana in your pocket, or are you happy to see me?"

"Actually neither its just a flacibo...."

Flacebo 

Flacebo is a word that combines "placebo" and FLAC(Free lossless audio codec) and implies that it is in fact indistinguishable from higher bitrate mp3 or other codecs.

- Man, I just physically can't bring myself to listen to music if it's not in .flac format... What should I do?
- Dude, its a flacebo, you literally can't tell the difference between flac and mp3.

Flacido Domingo 

Slang for flaccidity. A chick has to be truly busted to induce "Flacido Domingo." Because as most guys will readily admit - they will pretty much bone anything with a heatbeat.

See that Flacido Domingo at the club dawg? Damn was she busted! I went from FBW to Flacido Domingo in less than a second.

Flacibang 

Relentlously banging a woman (or man if so inclined)for long after ejaculation has occured. The result of the flacid penis and continual pounding is swallen balls and a thick soapy liquid build up that has a foul odour similar to fish and a strong stilton mixed together.

Steve flacibanged Sarah all night. She loved it but insisted on opening a window.

Flacido 

Name used for a guy whose sexual performance actually supercedes expectations for all the girls he has"loved"!!
A 'Flacido' is a stealthy stud of mixed breeding who is committed to identifying his future self to that of his sole icon...his absent father.
Hence, the pathetic, floppy pattern of the charming soulless womanizer continues.

Flacido is a man reaching his fifties, who talks about those lucky lovers he's "porked" over the years.Then,if you're lucky, he might boast about the career (he managed to barely salvage), and say "So,... wanna get porked?"
