This meme comes from a rapper who has a very decent following online. Basically, a rapper named Los had a mixtape come out on December 5th, 2011, Called "The Crown Ain't Safe". "The Crown" being who is crowned best in rap. Since then, the inte lornet (as it usually does with anything the slightest bit above average) has been going nuts over it. It has now gone to pictures. Some are just pictures of notable people with some type of nervous body language coming from them, with the words "{Enter Person's Name Here}, After hearing that the crown ain't safe." near their face. Though, this is the most popular variation, there are others. Any picture of someone or something with words around them, saying something having to do with the crown not being safe. The only catch is, it has to make sense, or else no one will get a laugh out of it.
