A term that refers to the process of getting on Youtube and finding yourself falling into an endless circle of video watchin. The process is caused by seeing an interesting video title on the side under the "More From" tab. Resulting in an rediculous amount of time spent on Youtube watching pointless vidoes, when you could be doing something useful with your time.
Man 1- "So last night I went to watch a WKUK video and ended up watching everyone of their videos, and then some, I spent 4 hours straight on Youtube."
Man 2- "Wow, that sounds like an intense night of Youtube Diving."
