Mamedoro【まめどろ】... Short for 'mame dorobo.' Refers to someone who sneaks out at night or has an affair with another man's wife, etc. Means a diligent thief. I worked as a long-haul truck driver in the red-light district and lived peacefully with my serious and kind wife. Due to work, I often left home for about a week. One day, I happened to run into an old friend and ended up letting him stay at my house for a while. However, when I returned home from work one day...! 'This mamedoro here aaahh!!'
