It means I love you so much I might punch someone if they say anything bad about you. I like you. I care about you. I might even be your sidekick.

I’m crazy about you, and I’ll punch my brother if he insults you.

I’m crazy about you, and I’ll fight your enemies for you.

I’m crazy about you, and I’ll wear your shirt to school.
