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.
The most hardcore wanka on the planet. Definitely a drug dealer from a long line of Italian mafia bosses. If you ever meet a Leo Galleywanka hide your food as he will scab off you till the ends of the earth. Hide your children if you come into contact with one as his filthy mind will plague them. Galleywanka's commonly resemble vampires with their fang-like teeth but when you get to know a galleywanka your life will be filled with laughs and good times. A Leo Galleywanka will always procrastinate, and often watch entertainment with adult content(GOT) instead of completing work, whether it be assignments or studying for maths tests which he does exceedingly well on. His name is properly pronounced Lao but he has given up on trying to correct people. If anyone offends a Leo Galleywanka they will be hunted by a Big Bax and a Ralfano, and then killed until they are dead. A Leo Galleywanka is a pure human with a tainted mind that loves to laugh, have a good time, and wank.
OMG, Leo Galleywanka, hide your food lads
YO, look at that Galleywanka

Although it is extremely painful for the victim, it tends to be considerably funny to people who witness it.
Today in the baseball game the pitcher took a nutshot; the baseball hit him in the nuts.
Man, I just watched the funniest nutshot video ever.
