A person who has devoted their entire being in to the practice of Waluigism, also known as that kid Lucca, who brought his Waluigi shrine to summer camp.
The Waluigism Priest shall now sacrafice a Nintendo 3DS to Waluigi, ALL HAIL THE GREATGOD WALUIGI!

A rumor actually says that Waluigi is the father of almost all people on earth, and thats why nearly everyone can go WALUIGI MODE.
When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
