2. In Homestuck, the quadrant of love represented by a spade that stands for hate love
When a pair of adversaries delve into this quadrant, they become each other's KISMESIS. As one of the concupiscent quadrants, it plays a role in procreation as well. There is no particularly good human translation for this concept. The closest would be an especially potent arch-rivalry.
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.
Jason: "So yeah, I booked a 36 hour flight halfway around the world for a fivesome with these four homeless girls. 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."
