Kryptonite Wank

A wank which leaves a person exhausted and weak because of the repetitive, strenuous motion of the arm.
The person ends up almost as weak as Superman when he is exposed to Kryptonite.

Person 1: Hey, want to go to town today?
Person 2: I cant, sorry, I'm recovering from a kryptonite wank.

white man's kryptonite 

An attractive women/girl of East Asian, Southeast Asian, or Pacific Islander decent.
Asian girls are smart and have figured out that all's they have to do to control the white man is to tilt their head to one side, while bating their eye lashes, and make a peace sign ( some times while pouting their lips) see kawaii . This will immediately cause the white man to fall under their spell. He then will proceed to carry things for her, make car payments, and watch Korean drama s. While other kinds of men are affected by Asian girl mind tricks the white man seem to be particularly susceptible, and lacks very little immunity to Asian cuteness.
see also yellow fever.

" I went to Hawaii, and its filled with white man's kryptonite. So, we decided I should stay permanently and buy a condo. I think I will put it in her name too".

my kryptonite 

Used to refer to something that is your ultimate weakness, that which renders you powerless...in reference to Superman...whose only weakness is kryptonite.

Overthinking is my kryptonite. Or Chocolate is my kryptonite. Make sense?
