Blacktop Blerp: The Beginning

Katy Perry.  Last Friday Night.

It goes like this: "...it's a blacked-out blur but I'm pretty sure it ruled - Yeah!"

I heard?  "...it's a blacktop blerp...."

I thought to myself, this can't be right!  And what on earth is a blerp?!

(And actually, it looks like I'm not the only one.  Found this when I was trying to confirm the line above.  It's no blerp, but they heard "top" too.)
