A person who contributes little or nothing to a given situation. Although you find galleywackers everywhere those in the workplace are the most annoying because they are likely receiving the same or greater rewards while doing little of the actual work.
Jeff was exactly right when he said the Roberts crew was a bunch of galleywackers.
honest alternative name to the band Framing Hanely. This band is gay as fuck. Their music is so terrible, it's likediarrhea for the ears. Only dumb drunk teen girls would enjoy this gay shit.
My girlfriend is going to the Flaming Gayley concert tonight, she better not fuck any of those douche bags unless she wants to break up and contract herpes.
