Just implement QoS on the router and limit him to 3 K/s. That'll sort him out.
Better yet, go into the YouTube player's cog (settings button) on a video, and, change it from streaming at the highest quality, and set it to 240p, or something like that.
If you don't do that, it'll stream at 1080p based on your connection, meaning, your megabytes are being stolen.
