A hype crash is a let down. It's when someone over promises and under delivers. When someone builds up the hype for something (i.e. a story, product, event, person, etc.) so much that when they finally tell you what it is, it's a major let down.
Movie Announcer: In a world...
Dude: Oooo new movie what's this?

Dude: Been done before, but sounds promising!
MA: ...and fantastical beings come to life like never seen before...
Dude: Tell me what it is!

Dude 1: So the craziest, most exciting thing that has ever happened to anyone in the history of the world just happened yesterday!
Dude 2: Awesome! What is it?!

Dude 1: I got a free slice of pizza!
Dude 2: Man, that's a total hype crash! Everyone has had free pizza before.
