Rarely known as TJT, "The Jerk Trap" is a term that describes a common cycle people go through while watching internet pornography. The cycle starts when one is ready to "finish", but is determined that they can find a better video to do it on.
The video in the thumbnails seemed 10x better than the video I was watching, so I waited to view the new video. Next thing you know I did exactly that over and over, I've got eighty tabs open, It's an hour an a half later and my balls are blue. The Jerk Trap gets me every fucking time.
