Where- USA East Coast, Gotham to be specific.
Short of hunting down a twelve year old boy and asking him, googling slang, pre teen slang and asking around I haven't had much luck.
How would the aforementioned pre-teen boy describe a time that was perfect, blissful, wonderful? He's remembering wandering off at a museum and ending up in the geology exhibit all on his own. And for this kid it's as good as it gets. (yeah he's a geek, but a rock hound geek.)
