'pedestrian' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.

(Other definitions for wake that I've seen before include "late party" , "Vigil held over a corpse" , "Ship's wash" , "Vigil before (or party after) a funeral" , "Come to - track of boat" .)
