I thought my kid was playing a multi-player game online but no, he is watching a video of a video game in which some players were griefing other players.
Little cartoony guys are running around with big guns and yelling at each other. The voices are provided by the annoyed griefed (or would it be grieving?) guys. Lots of "get out of the way, faggot!" Although there is an amusing bit when they argue about bile. Liver, ya moron. Not the spleen.
Apparently it is very funny. Here, You too can enjoy hours of fun watching people pretending to be characters pretending to kill for fun. **Makes the fishing channel look almost real.
**although I guess that's the basic idea of sitting around and watching say, Good Fellas or MacBeth. . .
