A particular way of talking, or an accent. It involves jutting the low part of the jaw forward and manipulating your tongue in a way that you make a sort of childish "schnarf". Best used to exaggerate what you're talking about something with passion. Form of dialect used mostly in the Pacific North West.
*Schnarf* "Their was this one time where I was hangington out with meh friendzorz and we had the bestest time evarr"
