Cancer of the dick.
Development is due to too much masterbation while watching hentai.
Involves several pros and cons.
Pros:
Your dick gets bigger due to uncontrolled growth of the dick cells, (And bitches love big dicks).
You don't have to worry about being raped by a
fat Maori whore because it's contageous.
Cons:
Your dick won't look like a dick no more, (although it gets bigger).
Your dick
will fall off after few years of cancer development, and a dickless
man will die.
"Fuck that guy has dick
cancer!"
"Shame, that fat Maori bitch caught my dick
cancer."
"
Man, stop watching hentai. You gonna get the bad case of dick cancer."
