Lil Uzi Vert isn't for everybody.

But the fans at last weekend's Hard Summer Festival in Southern California were certainly feeling the Philly rapper.

Here's video of crowd adoration getting so intense that Vert was forced to start running and then jump a fairly high chain link fence.

This appears to be the same festival in which Desiinger got so turnt that he puked on stage.

So maybe there was something in the water ...
