Something visually appealing to men, so appealing in fact that they immediately become aroused and consider it (porn, girl in bikini etc...) worthy of fantasizing about or looking at while masturbating.
Wow, did you see the new issue of playboy?? Now that's good jerkins!!
The use of doublespeak and/or jargon to allude to an answer, and to elude a question. It can be read backwards as well as forewards simply because it's non-linear; linear perspective indicates no answer.
I had to sit through ten minutes of Jerbish on a YоuTube video. Even though it seemed like some point was being made, I distinctly recall not having discerned any intelligible information. I reached over to close the video and gasped in horror at my own reflection. My now 'mouth' was.. (open?), as if basking at the sudden realization. And my 'hands' too, as if the sight of them could bring me to my many feet in head-splitting agony. I passed out. And when I came too, I peered over my bed to my limbs, terrified of what I might see. "Oh, thank Yith." I said.
