Georgia Nicolson is the main character in a book series by Louise Rennison. Georgia has her own unique way with the English language, coining words and terms at the drop of a nunga nunga. Therefore, any young, naive, loquacious girl might be termed a Georgia Nicolson and perhaps the action of coining terms could be known as "doing a Georgia Nicolson".

Georgia Nicolson quote: "We are going to Hamburger-a-gogo land! Honestly"
Fogey/fogy /fougi/ sl. (early 18C+, orig. Scot) old-fashioned, stuck-in-the mud.
Person with old fashioned ideas which he is unwilling to change: Come to the disco and stop being such an old fogey!
You think me an old fogeyand an old tory, his thoughtful voice said. I saw three generations since O’Connel’s time. I remember the famine. Do you know that the orange lodges agitated for repeal of the union twenty years before O’Connel did or before the prelates of your communion denounced him as a demagogue? You fenians forget some things. (James Joyce, Ulysses. PenguinBooks,1992. p. 38)
