Someone who doesn’t know how to swim who thinks that they are so awesome and praise themselves so highly that they believe that they themselves are god, they try to walk on water and drown due to the fact that they cannot swim.
Father at the funeral: “how did my son die?”
The friend: “you see he was into awesomism, so he believed that he could walk on water.”
Father: “but he couldn’t.”
The friend: “I know, but he thought he could.”
Father: “what idiot came up with that word awesomism anyways?”
The friend: “your son before he died.”
