I’m mixed about the OP image, because even though the picture is cool as fuck I don’t want some idiot to think I’m on their side if I have a t-shirt of it.

This one, then a sweet backpiece with the demon head in profile superimposed on some just CRANKING THEIR HOG with a pro-LGBTQ+ message? Fuck it, I’ll take 20.

So I thought “CRANKING THEIR HOG” was a euphemism for masturbating but now I am having doubts.
I’ve received a few replies with “cranking their hog” is that a reference to something? Is it from a movie or what?
I think it means masturbating and increasing the revolutions of a motorcycle.
