A guy that thinks he's the shit, and spends way too much time in front of the mirror. He puts tons of gel in his hair, and usually has at least one earring. He is the guy who rolls up his short sleaves and puts cologne on to go to the gym. Generally in a frat.
That sweet bro over there checking out his own biceps is totally fratastic.
Named for the infamous Canadian, N. Walpole, walpoling is the conscious decision to irk the living crap our of everyone around you by constantly pointing out the one thing that separates you from them, to point out that in one tiny area you are a have, rather than a have not. The true joy comes from knowing that soon, the walpoler will soon be just like everyone else.
"Dude, Nathan just walpoled me about his damn car again!"
"It's an element. That's more like he Dorsey'ed you."
Also the inspiration for the Fight Club Halo 2 Clan, informally called "The Walpolers"
"Dude, these kids on the Halo 2 are getting walpoled"
