What does Cracked in Fortnite mean?

Kamo always says the word "cracked" in his videos. For days I've been trying desperately to decipher what that means.

Hi, it's actually just cracked or broken

You usually say shield crack or shield break which means that the shield is broken so the opponent has no shield

When you say in a fight it usually means that he has no shield. If he says it if he doesn't break a shield, it simply means that the opponent is good, so sick

My love is so sad
