The drama queen
Any group of friends has a drama queen. While at first, he/she steals the show with all the drama and the fun that might come along, you soon realize that all they want is endless attention.
In order to GET that attention, sometimes they might cause a scene out of anything. Drama queens will amplify and distort reality, start untrue rumors, and post-dramatic things on their social media, so they can get the attention they crave for.
They are very immature and always end up embarrassing themselves. Even if at first it can be funny, it will soon start to bother you, because it can easily get exhausting.
