This is the ABSOLUTE horniest and desperate a person can get, even surpassing the likes of Down Cataclysmic and Down Catastrophic. You get so horny, that you do the most questionable shit. And you don't even get hit with post nut clarity because that's how down bad you are. You will do ABSOLUTELY ANYTHING for dick / pussy. Basically, your dignity is no more.

The plane is really old, and in worsening condition, and there is a lot of murder and violence in their country, but I just want to stick my dick into some pussy. I haven't had that in months. I was tired of waiting, so I jerked off to their voices."
