Your comment about fast talking, witty and snarky characters and dialogue reminded me about the show gilmore girls. Here is a description from tv tropes with some editing to avoid spoilers

Former Anchor series of The WB. Roughly equal parts Teen Drama and romantic comedy.

The show's central premise is this: the Gilmore girls are, more or less, two sides of the same coin. Mother Lorelai was born to privilege, but saw her education cut short by her pregnancy at 16. Daughter Rory, despite having been born in comparative poverty, is a gifted student. Both women are intelligent, witty, cynical, cute, and comically dysfunctional when it comes to men.

The main characters are complemented by a strong ensemble in the townsfolk of Stars Hollow, Connecticut, including an assortment of Nosy Neighbors: town selectman Taylor, who rules with an iron fist; Kirk, the village idiot who has dabbled in hundreds of professions; and Luke, owner of the town diner.

What really sets Gilmore Girls apart from other shows of its type is the heavy use of clever, fast-paced wordplay. Really fast. Think Aaron Sorkin on crystal meth and Seinfeldian Conversations.

Most episodes employ some form of Two Lines, No Waiting following the exploits of mother and daughter, though in later seasons, the plots more often alternated between the two from episode to episode.

The show also seems to take a particular interest in music. In addition to a number of music-obsessed characters, numerous musicians—including Sebastian Bach and Carole King—have held recurring guest roles. Others, like Paul Anka and Sparks, have had cameos or guest spots.

I am pretty sure Nossy would like this show, I know I enjoyed it thoroughly during high school (saw the first couple seasons in high school didn't finish it when I moved to college, came back years later and watched it from beginning to end on dvd.)
