HFY
Humanity Fuck Yeah!
Used as a general reference to copypastas that feature humanity being portrayed in a favorable light, normally in-comparison to other (alien) races. Often futuristic science fiction, some of these copypastas can get quite long.
Example HFY:

"The devil,” said the Felaran, “the devil brought you.”
I saw the human inhale deeply, its chest swelling before it took a wad of burning brown paper from its lips.
“No, buddy,” the human said. “We’re the ones at the helm. The devil’s just along for the ride.”
