Is it a contraction of two words "linguistic" and "drastic" ?>>>"Linguastic!"
I wouldn't be surprised, as English like contractions at least as much as siglas!
E.G. for contraction : "Drella" (Andy Warhol's nickname, contraction from "Dracula" and "Cinderella)
E.G. for siglas : "J.A.P. : "Jewish American Princess"
