Bean Mud [Mamedoro]... short for Bean Thief. A term referring to someone who secretly has sex with another man's wife, implying a stealthy, habitual intruder. I'm a hardworking long-haul truck driver, living a quiet life with my kind and faithful wife. Due to the nature of my job, I often had to be away from home for about a week at a time. One day, I unexpectedly reunited with an old friend. We got caught up in conversation and I invited him to stay at my place for a few days. But when I returned home from work, the sight that greeted me was...! "You damn bean thief, aaaaah!!!"
