The act of having sexual intercourse when an erection cannot be achieved because of excessive alcohol consumption. This can be similar to a "whiskey dick," but the flaccid penis is forced / pried into the vag. There is usually no motion involved because of the flaccidity, therefore the penis usually just sits inside and marinates. The receiver rarely receives any pleasure from the experience, and the penetrator usually gives up or passes out with it inside.
That girl got flaccid mashed last night.

I got laid last night but it was a flaccid mash and I'm pretty sure she received no pleasure from it and will never hear from her again.

While at work, Wanda stopped by the break room and bent over to pick up a quarter that someone had dropped. Roger saw this as an opportunity to give her The Flaccid Joey and briskly walked past her.

(noun) an argument (for a paper or essay) that starts out weak and limp but that gets longer and stronger the more you play around with it
My philosophy paper still has a flaccid argument, so I'm thinking about spending the night in the library to really firm it up.

Jimmy always has trouble with flaccid arguments, so he often asks his girlfriend to help out.
