The "THE_PACK" community is a parody of US biker (motorcycle) culture, where many men refer to their motorcycle as their "hog".
"Hog" is also a slang term for a man's penis.
"Cranking my hog" is slang for male masturbation. I think it's also used to refer to revving up one's motorcycle in the biker community, but I'm not 100% sure of that (my old man was a biker so I am loosely familiar with some of their slang).
They intentionally misspell "hog" as "hawg" for fun. So it's just a bunch of guys standing around jokingly referencing masturbation under the guise of talking about riding their motorcycles.

Specifically a hog is a Harley (or really any touring bike now), large, slow turning, and they start with H, and yeah you could call racing the engine (the vroom vroom throttle thing) cranking, though that's more of an action on older motorcycles you'd do to actually start the thing
The term from male masturbation actually comes from crank-start engines
"Cranking your hog" could be used as euphemism for male masturbation, but the "joke" is that it's probably the most ridiculous way you could refer to jerking off.
It also could be used to mean cranking the throttle on a motorcycle.
So THE PACK (the "wolf" pack) is kind of a mix of taking the piss out of: edgy/hardcore biker t-shirts/culture, ridiculously over the top support groups, occasional "wife bad" boomer humor, and the fact that a lot of "strong male" branded stuff is just a hair away from being extremely homoerotic. They're also legitimately just a fun group of general positive supportive posters.
I DON'T MIND DOING THE DISHES BUT I'D RATHER BE CRANKIN MY HOG WITH MY BROS
