You know what day it is.  You know!!!!  Don't look at me like that.  It's 4chan Friday.

Tonight, we have /y/ and /u/.

No, this has no connection to the creepy "y u no" guy.  It's actually about homosexuality.  Yes, they stand for Yuri and Yaoi.  If you don't speak Japanese, then you're probably better off.  Yuri and Yaoi stand for gay relationships in anime between women and men, respectively. 

Yaoi is a funny word, but after scrolling quickly through one page of penises, I quickly closed it.  I prefer Yuri, even though the word isn't as commonly used or nearly as funny sounding.  As I've said before, boobs usually rank higher on the interest scale than other things. 

Of course there is no shortage of boobs in anime.  It's common in animes to see many males (and some females)  get a nosebleed whenever they happen to see them as well, sometimes causing them to become "overdrawn at the blood bank."
I just gave blood today, so I'm familiar with donating, but Characters like Zoro from One Piece need to think about a withdrawal program, especially after losing five or six pints of blood in one fight, despite the human body only containing that much.  But as long as he has enough bandages, he should be fine.
