The unofficial name for males between the ages of 15-30 who lift the suspension of thier trucks to retared proportions, drive fast, cut people off because they can, speed up through puddles and speed bumps after which they usually yell, "YEAHHHH!". They are unusual in the way because they have many douchebag qualities but have more testosterone than any one person should possess, thus making them harder to classify. Also known as Assholes, they love to look for fights over everything and anything, including a slight look in thier direction, thier girlfriend or even thier trucks. Usually easily spotted from a distance because of the stickers on thier trucks or thier clothes, which consists of everything from Metal Mulisha to Famous Stars and Straps to No Fear and many other companies. These creatures originated in Southern California in Orange and Ventura Counties, but have since spread throughout the rest of the Western United States and as far inland as Texas. They should be approached with caution and possibly avoided at all times.
"That fucking Yeah-Guy just cut me off doing 85!!! Asshole!"
