aka ck when a girl sees condoms and immediate becomes weakened at the site of them. So weak that they will forget about there initial tasks and have one thing on the mind. using that condom as an accessory to "dress up" the mood.
I was going on a rant about how we fight so much, and he just pulled out condoms. I immediately felt weakened and i could only think about one thing, what goes in the condom. It was condom kryptonite.

This is a person in which you typically would not be attracted to for a variety of reasons. Probably someone you wouldn't even be friends with. Yet for some unknown reason, when you are around this person, you start acting out of character. Your brain short circuits; common sense goes out the window; and your body goes into overdrive. You start disregarding your regular social norms and sometimes moral code. You want to act on purely erotic and selfish emotions. This person becomes an adrenaline rush. You become addicted, wanting the next high. Yet when they aren't around, you are back to your typical good person self. The best course of action is to avoid the red kryptonite because the price you will pay is rarely worth the experience.
That man is the red kryptonite to my inner Clark Kent, and I'm about to go very, very bad.
