A Damsel is a young unmarried woman, and presented in a diminutive stature. She is unable to defend herself, or protect herself, and requires the attention of a handsome strong man to rescue her.
A Bachsel is a young unmarried man, and presented in an incompetent stature. He is unable to fix or repair things, and often is at the mercy of the environment around him.
It seemed to me that it was most unfair that there was a term for a woman in distress, but not a man is distress. In the modern era it has become increasingly apparent to me that there is an increasingly large population of men who are simply incapable of doing things. Just as the Damsel could not defend herself from robbers, bandits or voracious dragons, the Bachsel is the insolent useless product of a modern culture.
The proper bachsel is young and attractive, spending a good deal of time at the gym and if not at the beach, a tanning salon. Terms like manscaping, soy lattes, and other unmasculine behaviors come to mind. The bachsel cannot change a tire, or fix anything beyond turning it on and off. He must be rescued by an outsider.
The counterpart to the bachsel is the Dame, or the Lady Knight who is competent and able to take care of herself and can rescue pretty little boy toys.
