(You found a video on youtube that seemed normal at first but you started watching it and found out that you couldn't stop watching it for long. The video never seems to end and it's both addictive and hypnotising. Often if you're watching it in private you'll lose control and either go into a trance or do something to yourself. It's almost impossible to stop and you also find yourself wanting to show it to other people. If you show it to anyone it will hypnotise them too)
