manly way would be taking a knife and hacking it off
use a sharp fillet knife, a flexible one if you have
cut an inch or two of the skin away from the meat
put the fillet skin down on the cutting board (or counter top if you're a lazy bastard like me)
work the knife back into the cut
use the other hand to grab the skin thats already peeled away (rub some salt on it if its too slippery)
hold the knife at a downward angle and pull the skin and fillet away from the knife
if done correctly, you'll have a really nice clean cut - with no meat on the skin, and no skin on the meat
btw, if you're grilling it or backing it - leave the skin on
it peels off really easily when cooked
