a Muldoon is a male between 25 & 75. They rarely exceed 140 lbs. No job, cut off jeans, trucker hat, stolen sunglasses, cheap tennis shoes or flip flops. Tee shirt usually advertises a national brand beer. His most prized posession is his customized cruiser bike with a seat with springs & high handle bars - 1 speed with coaster brake & a plastic cup holder. Muldoon drinks canned beer in a paper bag.
The Muldoon has an incredible memory for bullshit trivia. Favorite songs include "Hotel California", Maggy May", & "Heart of Gold". Often found in Key West, Hatteras, Margate, NJ,... Ft. Lauderdale is Muldoon Mecca. Muldoons avoid the beach and more often frequent the docks, municipal jail cells, & emergency rooms. The Muldoons girlfriend is a Patti. Pattis have pretty faces with red noses, saggy titties,a hard gut, square asses, and skinny "drinking legs". Pattis are light hearted, Muldoons are often melancholy... under the boardwalk is not just a song, it's a way of life!
Bubsy: Hey, what happened to my beer?
Ed: That Muldoon asked if you were finished & I gave it to him.
