Hanna-Barberian
A passionate fan of the cartoons produced by the Hanna-Barbera animation studio; alternately, a collector of anything relating to Hanna-Barbera's cartoons, including toys, books, dolls, T-shirts, video games and even animation cels. Patterned on "old boy," a common term for graduates of English public schools (with variants such as "Old Etonian," "Old Harrovian," "Old Reptonian," "Old Wykehamist," etc.)
Imagine the typical Hanna-Barberian at ComicCon: hopelessly enraptured in that world of Saturday mornings past, wearing his Flintstones T-shirt and unable to resist passing by the booths of such selling memorabilia from those shows he wasted Saturday mornings on.
