1 definition by David E. Woodard
Person who try to stuff massive amounts of luggage, bags, gifts, coats, and other crap in the overhead compartment of the airplane. The most egregious overhead-hog is one who attempts to put all of his/her stuff only in the overhead compartment above their own seat--even though that particular compartment might already be full.
"That obnoxious overhead-hog held up the line while trying to stuff a bunch of Christmas packages in the space above his seat. It was clear that the packages wouldn't fit!"
