look up any word, like donkey punch:
 
1.
The rhythm guitarist for the Grateful Dead. Often overlooked because of Jerry Garcia's amazing lead guitar work, but still a talented player and a fundamental part of the Dead's sound.
Bob Weir has an upbeat country-sounding voice and sang Dead songs like "Mexicali Blues", "Sugar Magnolia" and "One More Saturday Night"
