What is Kchan?
1.
(kay-chan)
A representation of a diseased phallus.
Coined in the 17th century by a Chinese philosopher Wang-Kock, the Kchan was an illustrious example of what a penis shouldn't be. It was the metaphorical symbol used to indirectly describe a lack of manhood, a huge degree of promiscuity, and an unfortunate creation of evolution gone wrong.
It is now used to describe someone or something who most likely has a diseased phallus.
Man, I really thought that sex with Katherine's mom was going to be good last night, but now I have a kchan. This sucks.
Holy shit, I blacked out last night and now I'm a kchan!
