Related to the Superman movies: Superman's weakness.The only thing that can hurt the man of steel.

My definition:

A man/woman that calls someone their Kryptonite means that they are their weakness. Someone or something they have to stay away from because they want it even though it's not good for them or will hurt them.

Someone you want but can't have can be called your Kryptonite.
-You like Jane?

-Yeah dude but I gotta stay away from her because she's got a boyfriend. She's my Kryptonite.

-I'm allergic to shrimp.It's my Kryptonite.

-You're like Kryptonite to me. I have to stay away from you.

If I go crazy, then will you still call me Superman?
If I'm alive and well, will you be there and holding my hand?
I'll keep you by my side with my superhuman might

The person or object referred to, for some reason, makes one lose one's resolve, rendering a person easily influenced or coerced to doing something they're usually not predisposed to doing. In other words, “kryptonite” in this context is a metaphor of “weakness”.
