To sheen (verb) - to perform an action that people would generally consider bad while wanting to convince everyone else, and often yourself, the action was a great thing.
The word comes from the standard practices of the celebrity Charlie Sheen. His ability to convince himself that the downward spiral of his life is living life well, and his attempt to make others believe that the downward movement of his life is really a good thing is the inspiration of the word.
Usage - “He has to know that calling his boss bad names is a stupid thing to do, but he acts like it was great. He was just sheening.”
“I failed my test so I’ll have to sheen the whole episode when I tell my parents.”
"His life is a mess, but he's sheened it well."
