I must be missing something?
What's the joke?
Christian, one of the contestants on Project Runway (season before the last one), used fierce like the world would end if he didn't say it once an hour.
He's hardly the first gay man to make heavy use of "fierce". I don't even watch
Runway except for the clips I've seen on the show
The Dish.
I first became aware of the usage of "fierce" by gay men when watching the season of
Curb Your Enthusiasm that had Larry David starring in the stage production of
The Producers. Later I noticed Tyra Banks says it a lot on
America's Next Top Model (again, via clips shown on
The Soup and
The Dish.)
And now, Gatorade is
fierce!
