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.
