first there was the zombie. The zombie grew weary, and nearly fell to dust. However, new light shone, and he was reincarnated as gravebane. Then the call of eternal slumber was too much for gravebane, but he left behind his knowledge in a being called deadman.

Deadman is the nickname of a person also frequently known as gravebane or gravebanezombie. He frequents eris-free irc network and is very helpful.
I talked to deadman the other day... the Halo party is on saturday night.

An anime/manga series set a few years after a severe earthquake in Japan. A floating man in a red suit comes into a high school classroom and kills all the students except for one, Ganta Igarashi. Ganta is accused of murdering all his classmates and sent to an amusement park-like prison called Deadman Wonderland, aka the most twisted prison in the world. Prisoners are forced to battle each other on live TV, have body parts removed, etc. While at the prison, Ganta discovers his "Branch of Sin," the ability to manipulate his own blood. As he learns more about this ability, he starts to realize he may finally break free, and get revenge on the Red Man that murdered his friends.
Person 1: "Have you seen Deadman Wonderland?"
Person 2: "Yes! It's so awesome and intense! I feel so bad for poor Ganta though!"

The act of a man edging for a 90 day period in order to release a nut so incredibly large it could lead to dehydration, seizures, cardiac arrest, or even death. The production is so vast and volatile that others within the “splash zone “ are often left with lasting mental and physical trauma. Although warned of the possible horrors, many men still attempt the “Vikings Deed” to this very day. Legend has it that every US president is the direct product of insemination via a Deadman’s Nut.
I heard Big Jon is the 75th day of the Deadman’s Nut, I hope Cait gets her Frog Toggs in time
