An ancient Welsh warrior lauded for his prowess in battle as well as his thirst for
Irish whiskey and English maidens, and renowned for clog-dancing on the bodies of his dead enemies while reciting poetry.
Has been adapted in the modern vernacular to
mean performing feats of manly strength and/or coordination with style while highly intoxicated (dancing, brawling,
etc) and then going on to enjoy the spoils of victory (
ex. getting laid for said feats).
