A Crunch is a serious bowel movement. A bowel movement so fierce and powerful that it becomes less of a simple action and more of an event. One's day can be completely centered around the acting of a crunch, such a time is referred to as Crunch Time.

When someone seems attractive from a far away distance or from the side, but when you look at them from the front or at a closer view, you realize they are in fact hideous. Derived from that moment when you go to step on a leaf thinking it's crunchy, but it doesn't crunch when you step on it. When used as an adjective, the proper word form is crunchy, as crunch is the noun form.
"Boy! I thought that guy was hella attractive when I saw him walking in the hallway. But when he actually passed me, I was severely disappointed. Whatta crunch!"
