In olden days, portrayed as a sweet, innocent, fawn-eyed girl who is naïve about sex.
"Girl" and "maiden" were once gender-neutral words that refered to a young person of either sex.
2) Short for iron maiden. A Mideval torture device used in Germany. Basically, it was a coffin. The head and body of a maiden were sculpted into it to give the machine more dignity and elegance. The insides of the doors were lined with spikes, which would pierce the victim, although not fatally, so that he/she would die a slow, painful death.
Girl 2: Yeah! Cutest. Thing. Ever. I love Maiden! <3
An homage to one of the most Maiden bands of all time; Iron Maiden
