Every single fucking time at the end of a YouTube video the person has to tell everyone to subscribe to their channel.
I know most YouTube dwellers are braindead fucktards, but come on. That shit is insulting. And I don't give a flying fuck, if your videos are being reposted to other websites. If you present interesting shit, people WILL find you.
It's also annoying, when you're enjoying a video and when you're getting closer to the end of it, 3 minutes of that is HURRRR SUBSCRIBLE TO MEEEEEE!!!1!!!! Bitch, I want my content.
