A person, commonly found in a bar, who frequently engages the most clearly damaged individual in the room despite warnings or signs of any kind. This term was coined by Florida singer/songwriter Michael J Weiss in his song entitled "Bar Martyr." This song tells the story of a situation involving the original Bar Martyr and his attempt to get the attention of a clearly intoxicated and crazy individual.
A Bar Martyr would ignore all warnings and attempt to pick up the easiest prey in the bar simply because it's the path of least resistance. For this person to be a true Bar Martyr, the reasons and warnings not to do so MUST be overwhelming.
