lolita
Synonym discussion
Sense: noun/1
Lolita and nymphet both originate from Nabokov's novel and refer to a young girl seen as sexually precocious, but nymphet is more literary and far less common in everyday talk. Jailbait is informal slang that emphasizes the legal danger (underage status makes sexual contact a crime) rather than appearance or manner, and it carries a stronger pejorative tone. Seductress applies to an adult woman who deliberately attracts others, so the age difference is a key distinction — it does not imply a child. Of these three, lolita is the most controversial and most likely to cause offence when used about a real person. For example: calling a teenager in a news report 'a lolita' would draw far more criticism than describing a character in a novel as 'a nymphet.'

Etymology
Comes from the name of the young girl in Vladimir Nabokov's 1955 novel 'Lolita'. The name itself is a Spanish diminutive of Lola, which is a nickname for Dolores (Spanish for 'sorrows'). After the novel became famous, readers began using 'lolita' as a label for a type of girl, rather than just a character name.
