the term 'teenybopper' is a mid-20th century american english coinage, a playful and slightly dismissive blend of 'teeny' (meaning very small or young) and 'bopper'. 'bopper' derives from 'bop', a style of jazz characterized by fast tempos and complex rhythms, and by extension came to refer to a young person who was an avid follower of popular music and dance trends. the word 'teeny' reinforces the youth of the subject. thus, 'teenybopper' literally constructs the image of a very young, energetic follower of fashionable pop culture, a meaning which has remained consistent since its inception, specifically denoting a pre-teen or young teenage enthusiast.

Structure: teeny (small) + bopper (one who moves energetically to music) - teeny: english (diminutive of 'teeny' or 'tiny'), meaning 'very small'. - bopper: english (from 'bop', a style of jazz music and dance, + agent suffix '-er'), meaning 'one who dances to bop music' or more broadly 'an enthusiast of a particular music or fashion style'.
