The act of running or speed walking next to a moving car on the passenger side to make it look like you are almost riding in the car. It is a must to make faces and keep speed with the car when it is slows down or speeds up. A proper Milwaukee Buck is done by letting the car begin to move then waiting about 3-5 seconds before getting up to the passenger side and keeping speed with it. The key is to not make it look like you are running and staying level like you are actually riding in the car. It is best to engage in a Milwaukee Buck on a side street or a Neighborhood while at night and wearing a baseball hat. This is done because it makes it much more hilarious than during the day because it is much creepier and it makes it look more like you are really in the car. The hat is optional but it adds to the full effect.

E- Ok bro
The process of becoming a gay buck. Shoving a buck antler up your anus. Refers to a guy buck soup kitchen, or a guy circle jerk, or the Milwaukee Bucks.
Steve, I really hated it when Mark and Stan Milwaukee bucked me. It was uncomfortable and queer.
