Painting the walls
When you are so bored or tortured that you would rather die and let your brains and cum splash all over the wall, like it's your final cum statement.
I was so bored, I shot my brains and cum all over the wall, like it was my last day on Earth.
That boring job made me so mad, I killed myself and painted the wall with my cum and brains.
I was so tortured, I died and my cum painted the wall like a masterpiece.
