A squad on youtube that consists of a couple of male British youtuber a. It is way better than team 10 will ever be. It consists of Joe Sugg, Caspar Lee, Oli White, Jack Maynard, Josh Pieters, Connor Maynard and Mikey Pearce.

They all live in London and regularly do videos together. Unlike Team 10, they aren't a business, they're just a group of friends. Also unlike team 10, they don't do it for views and they are actually funny and make good content.
Did you watch Joe Sugg's new video? He played Cards Against Humanity with the Buttercream Squad
