I could not be without all sorts of words from the Meaning of Liff:
grimbister - a block of cars on the freeway all moving at exactly the speed limit because one of them is a police car
I got caught in a grimbister just south of Ogden. It didn't break up until North Salt Lake!
jalingo - a kind of joyous scattering - e.g. the alacrity with which the grimbister breaks up after the police car exits the freeway
He threw breadcrumbs at the pigeons with utter jalingo
acklins - those weird tingles you get in parts of your body while you're scratching other parts
When I scratch the back of my knee, I get acklins in my left eyebrow.
