Jeffin'

Outdoor activity in Jefferson County Missouri, the greatest fucking county if them all. Often involves consumption of cheap beer (normally Busch Light). Most of these activities would be illegal anywhere else, but not in JeffCo, where you can do whatever the fuck you want.

Get the Beer Andy, lets go Jeffin' tonight!
