Lolita was the nickname of one of the principal characters in Vladimir Nabokov's novel Lolita. Lolita's actual name was Dolores, with whom the narrator, Humbert Humbert, develops a sexual obsession. In the book itself, "Lolita" is specifically Humbert's nickname for Dolores. Nevertheless, "Lolita" and "loli" has come to be used as a general reference to a seductive or sexually attractive young woman.
In the marketing of pornography, lolita is used to refer to a young girl, frequently one who has only recently reached the age of consent, or appears to be younger than the age of consent.
A nymphet is a sexually attractive girl, or young woman. The first recorded use of the term "nymphet", defined by The Century Dictionary as "a little nymph", was by Drayton in Poly-Olbion I. xi. Argt. 171 (1612): "Of the nymphets sporting there In Wyrrall, and in Delamere."
In Lolita, "nymphet" was used to describe the 9- to 14-year-old girls to whom the protagonist is attracted, the archetypal nymphet being the character of Dolores Haze. Nabokov, in the voice of his narrator Humbert, first describes these nymphets in the following passage:
I've been loving this guitar since a long long time
Just trying so hard to find
Just where I've been and we're I'm going
Got to keep that inside of my mind
Well it's alright
Cause it's alright
Alright
Well the rhythm of the music running through your soul
Well you ain't got time to grow old
And the stars will lit and the sun will shine
And you just gotta get it on
And it's alright
And it's alright
Alright
No i won't take long just to sing my song cause i gotta
get on my way
When the sky is blue and the times are great and you just
gotta get it on
Well it's alright
Cause it's alright
