Stiffer than a preachers dyck in a whorehouse. Self explanatory
Holy crap, that saying brought back a comment I heard last night.
Guy was a school administrator in a big city. He "said" he had to go to a bachelor party and it ended up in a stip club.
During the night, he got a tap on the shoulder. When he looked around at who tapped him, it was the preacher of the church they attended.
The preacher told him he wouldn't tell if he didn't.
Can't tell if the story is true but he swears it is.
