look up any word, like blumpkin:
n. A foolish or stupid person. A buffoon.
Though they may not be a proper spabbage, and indeed a normal person, any action or phrase which a person may perform, or utter (respectively) which is idiotic in some form, may cause others in the vicinity to call them a "spabbage".
Spabbage: "Herp derp,"
Normal Person: "You Spabbage!"
