An unhygienic, extremely ugly, emaciated-looking female; any fugly
female, such as a swamp donkey
, that resembles a swamp-like creature. The origins of this word are traced back to Tollund Man, a man who was hanged in the 4th Century BCE and whose corpse was removed from a peat bog in Denmark in 1950.
Sarah wouldn't look like such a Tollund Girl if she took a shower and were some makeup.
