This food is so hot my head is about to explode! It's hot but it burns so good! Five alarm chili. So spicy it brings tears to my eyes! It's so spicy, my lips are numb! I can't feel my lips anymore!

Hot as a firecracker is one that comes to mind.

Haha, yes, I need them for a public event:) Thanks!

Do you only want polite ones? ;p
