a person who has little respect for others, and him/herself. a thug has a below average iq and likes to take part in illegal activity such as, drug dealing/use, fighting, killing, etc. a thug will go to great lengths to protect his "turf," most likely a street corner, or a shitty playground. it's easy to spot a thug: on the corner, pants around the knees, bandana or doorag on head, peach-fuzz goatee and a diamond earing, "tough guy" look on face. a thug loves: money, drugs, 40's, extremely loud rap music, fighting, underage girls, being abnoxious, spray paint, doo-rags, weapons, and grills. thugs dislike: reading, smiles, puppies (with exception to pitbulls), rainbows, led zepplin, and skiing.
a thug likes to protect his turf and act like a badass, they are animalistic in their attempt to become an alpha-male. we can understand this by looking at nba's ben wallace. he personifies "thug" perfectly by his actions on and off the court.
