Kanker Sisters 

The Kanker Sisters( May, Lee, and Marie) are a trio of girls that have a crush on the Eds in the Cartoon Network show Ed Edd n Eddy. They frequently bully the Eds by kissing them and forcing them to play footsies by locking up their feet and wiggling their red toes for hours. They torture the Eds by using red lipstick to leave lipstick marks and red nail polish on their toes and fingernails.

The Kanker Sisters painted their toenails with bright red nail polish and then made Ed Edd n Eddy play footsies with them while the Eds screamed in agony.

kanker 

Dutch word for cancer. Used obsessively by Dutch youth, both in real and on the internet.

1. A word describing a deadly disease.

2. An adjective to anything. Making the word more "extreme".

3. A verb meaning to go away or to "fuck off". Considered very unfriendly. Should never be used by foreigners, because it will result in them getting beat up badly.

4. A verb meaning to be talking negatively about something or to curse on something. Very old fashioned.

1. Ik heb kanker. / I have cancer.

2. Kankermongool. / Cancermongol. (It should be noted that mongol is the Dutch word used to describe people with Down syndrome.)

3. Kanker op. / Go away/Fuck off. (No, seriously, don't ever use this.)

4. Hou eens op met kankeren op... / Stop being so negative about...

All uses combined:
Het maakt me niet uit dat je moeder kanker heeft, je moeten gewoon niet zo kankeren over het gebruik van het woord kanker en anders kan je op kankeren, kankerjong. / I don't care that your mother has cancer, you just shouldn't be talking negatively about the use of the word cancer and if otherwise you can fuck off, cancerchild.
