Jack ( a.k.a. Sean) McLoughlin is an Irish gamer who posts to YouTube. He is very loud and has a tendency to cuss. He recently hit 1.5 million subscribes. He refers to himself as "The Boss". He got his start in September of 2013, when the top YouTuber PewDiePie ( a.k.a. Felix Arvid Ulf Kjellberg) gave him a shoutout in a competition. He became famous from playing Happy Wheels and Skate 3, as he still plays Happy Wheels if you'd like to watch it but dropped Skate 3 as he ran out of stuff to do. He currently doesn't have a name for his fans and addresses each person individually and not as one.
