"Hey there u liberal lol. The thing about that is I`m not lol at all. How worthless are u really? Shut up when your talking to me boy. I noticed that in typical liberal fashion your app is like a Clinton, in that everything about it is fake. Why even have an app description and not explain to people that it will cost to use each and everything on that free app. Which to me kind of defeats the purpose of free download. Are you stupid boy? I bet you`ve been backhanded quite a few times in your day. If not, you will be and maybe sooner than you think. I`m here to genocide liberals... why you ask? Cuz this is America third world country. So beware"
