Youtube smack

A Youtube smack is when you call someone over, play a really long video, and at the end, reveal to them that it's a Youtube video. The purpose of this is usually to satisfy them with a good amount of progress so they can relax when they get back home. Sometimes, if you know each other well, this is done on their account, conveniently saving the progress for them. If it's on your account, they can simply buffer the end of the video on their account when they get back home and the video will automatically be finished for them.

Friend 1: I Youtube smacked Vincent yesterday.
Friend 2: Really?
Friend 1: Yeah. Now he's spending today just relaxing at home.
Friend 2: What video?

Friend 1: Since it was the only day we'd be meeting this week, I used a half an hour long restoration video.
Friend 2: Well it sure is nice to be satisfied, isn't it?
Friend 1: Yeah.
