A Parrothead is a fan of Jimmy Buffett (there is no other meaning). The typical parrothead is pictured to wear a Hawaiian shirt, flip-flops, and other tropical attire, and to enjoy drinking margaritas on the beach. Parrotheads often decorate their homes in tropical motifs. In general the life of a parrothead is one of relaxation and being on a permanent mental vacation even while at work.
I like listening to Jimmy Buffett's music, therefore I am a Parrothead.
