the guy above me sucks.
A hardguy is a real man. someone who can drink his body weight in alcohol. preferable O.E. He's an all around super sweet, awesome dude. He chugs liters of milk like it ain't no thang. When he goes out, he drops jaeger bombs and Sparxx like it's his job. See the youtube video for details.
Eric Kaufman is the ultimate harguy; he can chug a whole 30 rack in under 10 seconds. Watch him. Guys from Dartmouth are generally hardguys, but rarely do you find a guy harder than the Whooping Kauf.
