Denis' Theorem - also known as the Denis idea or Denis' identity - is The idea that there are two kinds of people.
The first type of people are Denis, generally slouched lazy people. They wear baggy sweatpants, are very bad at maths and have a thing for bigger girls.
The second type is that of the non-denis, people of non-denis decent are people who don't find themselves under the criteria of a Denis found above. Therefore everybody is either Denis or non-denis.
Person 1 (a non-denis): 'That guy is a total Denis, he got a D on his last maths test. Just look at him, he's letting his girlfriend Scran all his Din Dins!'
Person 2 (also a non-denis): 'I know right, look at his slouched posture and baggy sweatpants, what a Denis. We're far superior to him, Denis' Theorem I guess...'
Denis is known as a very energetic, crazy, silly guy. Once you get this guy hyped up it’s hard to control. Don’t get me wrong though he is crazy, he is also hilarious and can make you laugh until you cry.
