A hacking cough that is gained when one inhales the powdered sugar on a donut. Usually occuring when one is trying to eat the donut and talk at the same time, a dunkinhakkin is characterized by a dry mouth and inability to breathe before all the sugar melts away. Dunkinhakkins are also a great means for gathering odd stares and questions of "Are you ok, man?"
"This breakfast has given me a dunkinhakkin."
