Often seen with a sorostitute, a fraternitool is the stereotypical blowsed hair, off-center ball cap, pop-collared, complete tool (or 'spanner' if you're from Britain) member of a fraternity. Fraternitools tend to travel in small groups, and usually drink heavily to make up for their lack of personality and endowment.
"Jeez, that fraternitool's hat looks like it's about to fall off, and his collar is up around his ears!"
