Get a G-Man mug for your fish Günter.
A fake Christian manchild that is obsessed with other men and uses the bible as a weapon, although he misunderstands most of what it says. He thinks "debating" means yelling over other people and calling them atheists if they don't agree with him. Generally has a UTI and ashy knuckles and always claims he wins arguments although he has never won one to date.
That street corner dude is a real G-Man. Don't get too close!

Get the G-Man neck gaiter and mug.
A strange breed of boy that is characterized by the following:
a)A grotesque nerd lisp
b)little or no neck
c) an unwarranted sense of importance
G-men often physically resemble turtles. Although, when creating a mental image of a G-Man ,you must keep in mind that these creatures lack the cuteness normally associated with turtles. They have actually been known to be abused by desperate bulimics who have built up a tolerance towards ipecac and are looking for a quick vomit session. Yes, G-men are really that gross!
girl 1 :So the other day while I was walking around campus, I saw a G-Man doing the gator chomp and smoking a blunt.
girl 2:. Yeah I remember seeing him too. He tried hitting on me but I kindly declined.

girl 1:Yeah, its a terrible idea for him to do anything evocative of an amphibian . He is just drawing attention to his nasty swamp like aura.
