A "holy hootinany" is slightly different. Similar to a regular hootinany, this is a social event often sponsored by your local Southern Baptist congregation. The main difference: replace PBR with preaching.
"I got saved last Sunday afternoon, at that church barbeque. That Bible-thumping preacher scared the hell right out of me. Then they fed me till I about half died. That was a holy hootinany for the books."
