Immature as hell. Trolling is funny sometimes (and most of the time, the guy you're calling laughs) but this ain't trolling, its pointless harassing and time wasting.
If that's you on the call or on the video, then I would honestly like to ask you to grow up and come back to NGU/gaming when you do. If not, ignore this.
PS: Sorry for repeating what everyone else already said, I just wanted to add that last note.
Also, thanks for the info at the end of the 2nd video.
