Shane performed a self-castration after watching "twilight".

castration fantasy is when you dream about or desire or think about the woman you love to loving-ly remove your testicles or to keep them in HER possesion

My teenager refuses to take out the garbage unless I threaten him with electronic castration.

Roshan: "I don't want to date a potato."
Anna: "Roshan, don't be a hoe. You need spiritual castration."

I will self castration myself.

"I better not catch you pissing standing up!".
and that is an example of toilet castration.

Two people observe a crackhead with a knife.
Person A: Holy shit! He's got a knife!! What do we do?
Person B: Stay out of sight. Be ready to call the cops if he starts something.

Person A: Sounds like a good idea. But, what if he attacks us? Do you know any martial arts or have a gun?
Person B: Yes and yes. For now, we just watch...
*a few moments later*
Person A and B simultaneously "puke their guts out"
Person B: That crackhead just performed self-castration! Quick! Hand him a Darwin Award!!
