shinji's_fapping_hand_(meme)
A meme based on an infamous scene from The End of Evangelion.
The scene involves Ikari Shinji visiting an unconscious Souryuu Asuka Langley inside a hospital. After sitting next to her hospital bed for awhile, Shinji began to masturbate and ejaculate to relieve his stress while fantasizing about her. After looking at his own cum in_his_left_hand, Shinji realized what he had done and suffered a mental breakdown.
Commonly associated with the quote "I'm so fucked up" from the English dub.
